Description
Technical Field
The invention relates to the technical field of fuel cell catalysts, in particular to a preparation method of a fuel cell non-platinum catalyst.
Background
A fuel cell is a highly efficient, environmentally friendly power generation device that can directly convert chemical energy stored in a fuel and an oxidant into electrical energy. Fuel cell electrocatalysts play the role of a "factory" of electrochemical reactions and are a key material in the core of fuel cells. On the other hand, the current premise of the commercial application of fuel cells is to solve various problems of performance, cost, stability, durability, environmental adaptability, and the like, wherein the most critical is the cost problem. The cost of the battery catalyst is about 1/4-1/3, and the cost cannot be further reduced along with the expansion of the capacity. The main reason is that the electrocatalysts in the prior art use more platinum, and the platinum reserves are limited and expensive, thereby restricting the commercial application of the fuel cell.
The traditional fuel cell electrocatalyst is carbon-supported platinum, the main method is to support platinum with the diameter of 2-3 nm on the surface of carbon black, the preparation method is various, but chloroplatinic acid is mainly reduced and settled on the surface of the carbon black. The electrocatalyst prepared by the method has poor stability when the platinum particles are less than 2nm, and has low mass specific activity when the platinum particles are more than 3nm, so that the loading of platinum cannot be further reduced. The prior art is generally improved by alloying, for example, one or more elements of palladium, cobalt and nickel are added to form 2-3 nm alloy particles with platinum, so that the use amount of platinum is reduced, and the active reaction area of platinum is increased. However, the difficulty with this type of process is that the alloying elements are easily lost, i.e., the stability is poor, and the reduction in platinum usage is not particularly significant.
Disclosure of Invention
In view of the above, there is a need to overcome at least one of the above-mentioned drawbacks of the prior art, and the present invention provides a method for preparing a non-platinum catalyst for a fuel cell, comprising: (1) dispersing melamine and formaldehyde aqueous solution into 100ml of water, wherein the molar ratio of the melamine to the formaldehyde is (0.5-2) to (1-3);
(2) heating to boil by microwave to form a tricarboxymethyl melamine resin solution;
(3) adding 2g of porous activated carbon into 100ml of aqueous solution, adding 2-5ml of triton X-100, and dispersing to form carbon slurry;
(4) pouring the tri-carboxymethyl melamine resin solution into the carbon slurry, and stirring for 5-10 minutes;
(5) adding 10ml of 0.01-0.1M ferrous sulfate aqueous solution, and stirring for 5-10 minutes;
(6) obtaining a prepolymerization product after 90 ℃ water bath, and drying in a vacuum rotary evaporator;
(7) drying the prepolymerization product in a vacuum drying oven at 150 ℃ for 4-12h to obtain composite resin, and carrying out ball milling and crushing for 1-2 h;
(8) heating at 40 deg.C/min under nitrogen atmosphere, maintaining at 1150 deg.C for 0.5-4h, cooling to 200 deg.C at 10 deg.C/min, and cooling to room temperature.
According to the background art of the patent, the traditional fuel cell electrocatalyst is carbon-supported platinum, the main method is to support platinum with the diameter of 2-3 nm on the surface of carbon black, the stability of platinum particles in the method is poor when the platinum particles are less than 2nm, and the specific mass activity is low when the platinum particles are greater than 3nm, so the loading capacity of the platinum cannot be further reduced, the prior art is generally improved by alloying, but the difficulty of the method is that alloy elements are easy to lose, namely the stability is poor, and the reduction of the platinum dosage is not particularly obvious; in addition, the microwave heating technology is adopted for the first time to form a large amount of tricarboxymethyl melamine resin, the pH value is not required to be adjusted in the process, and the introduction of impurity elements such as sodium hydroxide, potassium hydroxide and the like is avoided; the non-platinum catalyst prepared by the method can be used for replacing the existing platinum-carbon catalyst of the cathode of the fuel cell. The oxygen reduction performance of the catalyst under alkaline conditions is higher than that of a platinum-carbon catalyst, the oxygen reduction performance of the catalyst under acidic conditions is also close to that of the platinum-carbon catalyst, the raw materials are wide in source, the cost is only equal to that of the platinum-carbon catalyst 1/100, the preparation can be completed through one-step pyrolysis treatment, the process is simple, and the catalyst is suitable for large-scale production.
In addition, the preparation method of the non-platinum catalyst for the fuel cell disclosed by the invention also has the following additional technical characteristics:
further, in step 3, the porous activated carbon is washed with 0.5M hydrochloric acid and dried.
Further, in step 3, 2g of porous activated carbon was added to 100ml of the aqueous solution, and 2 to 5ml of triton X-100 was further added, followed by ultrasonic dispersion to form a carbon slurry.
Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
