Hereinafter, the configuration and operation of the present invention will be described in more detail.

A second step of forming the oxidized Pd nucleus, a third step of treating the nanocarbon with the Pd nucleus formed with a strong acid, and immersing the strong acid-treated nanocarbon in an electroless nickel plating solution to form a surface of the nanocarbon.

Provide a method.
In the present invention, nanocarbons are classified into metallic nanocarbons such as CNF, MWCNT, TWCNT, DWCNT and metallic SWCNT, and semiconducting nanocarbons such as semiconducting SWCNT and SWCNT bundles.
In the present invention, nickel coating is used to include Ni-P or Ni-B coating, depending on the type of reducing agent used during electroless plating. That is, the Ni-P coating is formed when nickel is electrolessly plated using a phosphorus (P) -based reducing agent, and the Ni-B coating is formed when a boron (B) -based reducing agent is used. The

In the method for producing nickel-coated nanocarbon using the electroless plating method of the present invention, the first step is to clean the nanocarbon with ultrasonic waves in an organic solvent or an acid aqueous solution for the purpose of improving purity. It is a step. For example, it is possible to remove impurities such as amorphous carbon by immersing nanocarbon in an organic solvent such as alcohol or an aqueous acid solution and performing ultrasonic treatment.
Or a 1st step is a step which performs the thermal oxidation process in the air for 30 minutes-5 hours at 400-600 degreeC.
FIG. 2 shows the results of calorimetric analysis (TGA) of CNF before and after heat treatment. As shown in FIG. 2, as a result of performing thermal oxidation treatment in air at 400 to 600 ° C. for 3 hours, the purity of CNF increased from 87 wt% to 99 wt%. Therefore, the process of cleaning CNF using a solvent such as alcohol can be replaced with thermal oxidation treatment. The thermal oxidation treatment process is advantageous in terms of economy and environment because the use of a solvent or the like is reduced compared to the cleaning process.

The second step includes immersing the cleaned or thermally oxidized nanocarbon in a Pd-containing solution, causing reduction of Pd ions on the surface of the nanocarbon, and generating activated Pd nuclei on the surface of the nanocarbon. It is.
Electroless plating proceeds only on the activated surface of nanocarbon, and the degree of activation of the nanocarbon surface affects the adhesion of the electroless plating layer.
Therefore, in this step, the cleaned or thermally oxidized nanocarbon is immersed in a solution containing Pd, and Pd ions are reduced on the surface of the nanocarbon to generate activated Pd nuclei on the surface of the nanocarbon. By activating, the surface of the nanocarbon is activated.

When the nanocarbon is a semiconducting SWCNT or SWCNT bundle, the step of immersing the semiconducting nanocarbon in an Sn-containing solution and adsorbing Sn ²⁺ ions to the surface of the semiconducting nanocarbon, that is, washing with water, that is, sensitization treatment Includes additional steps.
When the nanocarbon is CNF, MWCNT, TWCNT, DWCNT, and metallic SWCNT, the sensitizing treatment step is not required. However, in the case of the semiconducting SWCNT and SWCNT bundle (bundle), the sensitizing treatment is performed before the activation treatment. .

The third step is an acceleration treatment step. In the case of metallic nanocarbons (CNF, MWCNT, TWCNT, DWCNT, and metallic SWCNT), the nanocrystals in which Pd nuclei are formed to precipitate purified Pd. This is a step of treating carbon with a strong acid.
In the third step, when the nanocarbon is semiconducting (semiconductor SWCNT and SWCNT bundle), the Sn component remaining on the surface after the sensitization treatment and activation treatment is removed, and purified Pd is deposited. It is. That is, the semiconducting nanocarbon undergoes Sn ²⁺ + Pd ²⁺ = Sn ⁴⁺ + Pd ⁰ reaction through sensitization and activation treatment, and Pd nuclei are formed on the surface. Sn ⁴⁺ remains on the nanocarbon surface, but is removed by treatment with a strong acid.

The fourth step is a step of immersing nanoacid-treated nanocarbon in an electroless nickel plating solution to form a nickel plating layer on the nanocarbon surface.
Even if the Pd catalyst is activated on the surface of the nanocarbon, in order for the autocatalytic plating reaction to continue, the temperature must be maintained above a certain temperature, and as the temperature increases. The rate of plating reaction increases. The nickel plating solution is classified into a normal temperature type nickel plating solution (reaction at 40 ° C. or less) and a high temperature type nickel plating solution (reaction at 100 ° C. or less).
The plating rate can be adjusted by adjusting the pH. That is, on the basis of 4.8, the higher the pH, the higher the plating rate.
Since the plating thickness increases in proportion to the plating time, the plating rate is adjusted according to the thickness of the target.

In the present invention, the fourth step proceeds in the range of 20 to 40 ° C. for 5 to 20 minutes in the case of a normal temperature type nickel plating solution, and in the case of a high temperature type nickel plating solution in 1 to 10 minutes at 70 to 100 ° C. It is preferable.
In the fourth step, the pH is preferably maintained at 4-6. When the pH is maintained within the range of 4 to 6, the electroless nickel plating solution can be maintained more stably, the plating rate is high, and the plating efficiency is excellent.
The method for producing nickel-coated nanocarbon using the electroless plating method according to the present invention controls the concentration of the plating solution, the deposition time, the reaction temperature, the pH of the plating solution, etc., and the metal loading, shape, and distribution density. , Particle size can be controlled.
The plating solution is classified into a high concentration plating solution (10 to 13%), a medium concentration plating solution (7 to 9%), and a low concentration plating solution (1 to 5%) according to the phosphorus (P) content. The As the phosphorus content increases, the plating rate decreases, the corrosion resistance increases, and the heat resistance decreases.

According to the present invention, the load of Ni—P, Ni—B or Ni, Ni—P, Ni—B or Ni can be controlled through control of process variables such as the concentration of electroless plating solution, deposition time, reaction temperature, and pH. Shape, distribution density or particle size can be controlled.
In particular, a fibrous Ni-P or Ni-B coating, a scalelike Ni-P or Ni-B coating, a spherical Ni-P on the nanocarbon surface through control of process variables. Alternatively, various forms of Ni-P or Ni-B coating can be performed, such as Ni-B coating.

FIG. 1 is a conceptual diagram of nanocarbon coated with palladium (Pd) and nickel (Ni) according to the present invention. As shown in FIG. 1, a fibrous coating can be realized when the reaction rate is low under the conditions of a large amount of Pd ions, a low temperature, and a low pH (standard 4.8).
Also, scaly coating can be realized when the reaction occurs rapidly under the conditions of a large amount of Pd ions, high temperature, and high pH (standard 4.8).
Furthermore, the spherical coating can be realized under the conditions of a small amount of Pd ions, high temperature, and high pH (standard 4.8), but the concentration of Pd that plays a role of seeding so that nickel ions can be laminated, and If the temperature and pH are high, nickel ions are deposited only around Pd while the reaction occurs rapidly, and a spherical coating is formed.

Specifically, in the fourth step, the concentration of Pd is 0.4 to 1 g / L, the concentration of the Ni plating solution is 5 to 10 g / L, the deposition time is 10 to 15 minutes, the reaction temperature is 70 to 80 ° C., and the pH is 4 to 5. By proceeding, a fibrous nickel plating layer can be formed.
The fourth step proceeds at a Pd concentration of 0.4-1 g / L, a Ni plating solution concentration of 5-10 g / L, a deposition time of 5-10 minutes, a reaction temperature of 80-100 ° C., and a pH of 5-6. Thus, a scale-like nickel plating layer can be formed.
Further, the fourth step proceeds at a Pd concentration of 0.125 to 0.2 g / L, a Ni plating solution concentration of 5 to 10 g / L, a deposition time of 5 to 10 minutes, a reaction temperature of 80 to 100 ° C., and a pH of 5 to 6. By doing so, a spherical nickel plating layer can be formed.
Nanocarbon with a fibrous coating has the advantage of high strength, and the nanocarbon with a scaly coating has a large surface area, which is advantageous for electromagnetic shielding and hydrogen adsorption, and has a spherical coating. Nanocarbons are advantageous for use as fuel cell catalyst supports.

The components of the electroless nickel plating solution are divided into a main component and an auxiliary component.
The main component consists of a reducing agent that donates electrons to nickel salts and nickel ions to reduce them to nickel. Nickel salt hydrates such as nickel chloride, nickel sulfate, and nickel sulfamate can be used as the nickel salt, and hypophosphite, borohydride, dimethylamine borane, hydrazine, etc. are used as the reducing agent. Is possible.
Auxiliary components include complexing agents, buffering agents, pH adjusting agents, accelerators, stabilizers, improving agents and the like, which are added to extend the life of the plating solution and improve the efficiency of the reducing agent.

The complexing agent plays a role in stabilizing metal ions by adjusting the total amount of metal ions participating in the reduction reaction by forming metal complex ions or by delaying the precipitation of metal ions as metal salts. Fulfill. Although the kind is not specifically limited, Organic acids, such as sodium acetate and ethylene glycol, and those salts can be used.
The buffering agent is used for reducing the change width of the pH during electroless plating, and the kind thereof is not particularly limited.
The pH adjuster is used to prevent a change in pH that affects the speed, efficiency, and plating film state of electroless plating, and the type thereof is not particularly limited, but ammonium hydroxide, inorganic acid, organic acid, Caustic soda can be used.
The promoter plays the role of promoting the plating rate and improving the metal deposition efficiency, and the type thereof is not particularly limited, and sulfides, fluorides and the like can be used.
Stabilizers suppress the occurrence of reduction reactions on the surface other than the surface to be plated and play a role in suppressing the spontaneous decomposition of the plating bath. The type is not particularly limited, but lead chloride, sulfide, nitrate Etc. can be used.
The improving agent plays a role of improving the gloss of the plating film, and usually a trace amount of a surfactant is added.

The fifth step is a step of crystallizing the nanocarbon on which the nickel plating layer is formed by high-temperature heat treatment, and is an inert gas (Ar, N ₂ , He, etc.) atmosphere, a vacuum atmosphere (10-3 torr) or air This is a step of high-temperature heat treatment at 300 to 700 ° C. for 3 hours in an atmosphere.
As a result of the fourth step, the nickel plating layer formed on the nanocarbon may be an amorphous nickel plating layer. Such an amorphous nickel plating layer can be converted into a crystalline nickel plating layer by thermal oxidation treatment. For example, when Ni-P or Ni-B is electrolessly plated on nanocarbon, an amorphous Ni-P or Ni-B coating formed by immersing nanocarbon in an electroless nickel plating solution is subjected to heat treatment. It can then be converted to a crystalline Ni-P or Ni-B coating.

In conclusion, the method for producing nickel-coated nanocarbons using the electroless plating method of the present invention includes pretreatment, activation treatment and acceleration when the nanocarbon is CNF, MWCNT, TWCNT, DWCNT and metallic SWCNT. It is characterized by plating after the treatment, and when the nanocarbon is semiconducting SWCNT and SWCNT bundle, the pretreatment, sensitization treatment, activation treatment and acceleration treatment are performed, and then the plating treatment is performed.
