Description
Technical Field
The invention relates to an application of a PtCo @ NC catalyst in a direct methanol fuel cell, belonging to the technical field of fuel cells.
Background
Direct Methanol Fuel Cells (DMFC) use methanol (CH) in liquid form3OH) as fuel. Direct methanol fuel cells are a variation of proton exchange membrane fuel cells that use methanol directly without prior reforming. The methanol is converted at the anode into carbon dioxide, protons (hydrogen nuclei or hydrogen ions) and electrons, which migrate through the pem to and react with oxygen at the cathode, and electrons through an external circuit, as in a standard pem fuel cellThe load reaches the anode and performs work.
Improving the activity of electrode catalysts is one of the keys driving the development of DMFCs. Pt is the earliest catalyst and has better electrocatalytic activity, and particularly has great advantage in reducing the over-potential of methanol oxidation. In addition, the noble metal Pt has higher corrosion resistance in an acid solution, so that the catalyst has better stability. To date, no better single metal has been found to replace Pt. However, the natural reserves of platinum are limited, the price is high, and the intermediate product of methanol oxidation easily poisons the platinum electrode, so that the research on the anode catalyst with high catalytic performance and poisoning resistance becomes a key problem for the development of fuel cells. The new catalyst system (Pt alloy, Pt-metal oxide, etc.) is adopted, which not only improves the activity of the catalyst, but also reduces the dosage of the platinum group noble metal catalyst, thereby reducing the cost.
Among the Pt alloy catalysts, Pt — Co alloy catalysts are a commonly used catalyst type. Nana Du et al (Nano Research, 2017, 10(9): 3228-typed PtCo nanoparticles derived from Pt @ ZIF-67: high-purity active and durable catalysts for oxygen reduction reaction) Pt nanoparticles were added to the synthesis precursor of ZIF-67, so that the Pt nanoparticles were adsorbed in situ to ZIF-67, and pyrolyzed at high temperature in a nitrogen atmosphere to obtain a nitrogen-doped carbon-stabilized PtCo Nano alloy catalyst (PtCo @ NC) having high electrocatalytic activity and being capable of reducing the cost of the catalyst. However, in the above preparation method, the Pt nanoparticles are very easy to agglomerate, and the addition of the Pt nanoparticles to the precursor for synthesis of ZIF-67 does not allow the Pt nanoparticles to be wrapped in ZIF-67 well, thereby causing a great amount of waste of Pt nanoparticle raw materials and increasing preparation cost invisibly.
Inspired by mussel adhesive protein, a research of Messersmith et al in 2007 finds that PDA formed by oxidation self-polymerization of dopamine as a monomer under the condition of oxygen and weak base has a similar structure with the adhesive protein and can be used as a surface modification layer of organic and inorganic solids. The large number of catechol and amino structures in PDA confers its characteristic properties: 1) adhesion, which can form a conformal and continuous coating on the surface of almost all materials due to the affinity of the bulk catechol functionality in PDA structures; 2) the hydrophilic property, the phenolic hydroxyl and the amino in the PDA structure can form hydrogen bonds with water molecules and are well dispersed in water, so that the hydrophilic property of the PDA can be utilized to modify the hydrophobic material; 3) biocompatibility, MTT method proves that PDA film is non-toxic, and in vitro cell is easier to grow on the viscous surface, so that the modified biological material of PDA has good biocompatibility and can be widely applied to biomedicine; 4) the chemical activity is that the phenolic hydroxyl and amino in PDA can react with mercapto, mercaptan and other groups through Michael addition and Schiff base to perform subsequent secondary reaction, and on the other hand, metal ions can be chelated through coordination.
Based on the prior art, the invention develops a method for preparing the PtCo @ NC catalyst by taking PDA as a surface modifier, and the catalyst is used for a direct methanol fuel cell. The method can effectively improve the utilization rate and the adhesive force of the noble metal raw material, reduce the preparation cost of the catalyst, has the electricity generation performance superior to that of a commercial Pt/C catalyst when being used for a fuel cell, and has good application prospect and economic value.

(4) preparation of PtCo @ NC catalyst
And (4) placing the Pt @ polydopamine-coated ZIF-67 obtained in the step (3) in a tubular furnace, and roasting at the temperature of 900 ℃ for 3-8 h under the protection of nitrogen to obtain the PtCo @ NC catalyst.
Further, the soluble cobalt salt in the step (1) is one or more of cobalt nitrate, cobalt chloride and cobalt acetate.

According to the invention, the nano-layer coating is formed on the surface of the ZIF-67 through the adhesion effect of PDA, and a large amount of phenolic hydroxyl and amino on the surface of PDA can form stable coordination bonds with metal, so that Pt is chelated on the surface of PDA @ ZIF-67 in a highly-dispersed manner. The metal compound is reduced by volatilizing a large amount of reducing gas from the organic compound framework and the poly-dopamine by roasting in an oxygen-free atmosphere, and meanwhile, Pt and Co particles are easy to shrink and close at high temperature to fuse to form an alloy. The PtCo alloy prepared by the preparation method has very small particle size, is only 3-6nm according to TEM representation, and is loaded on the surface of a nitrogen-doped carbon carrier in a highly dispersed manner.
