Preparation method of high-performance superlow-palladium-capacity anode electrocatalyst Pd-CoP/C of direct formic acid fuel cell

The invention relates to a preparation method of a high-performance superlow-palladium-capacity anode electrocatalyst Pd-CoP/C of a direct formic acid fuel cell and belongs to the technical field of fuel cells. The preparation method comprises the following steps: dispersing a carrier and cobalt chloride hexahydrate in water, drying to obtain a first compound carrier by distillation after ultrasonic dispersing and stirring; mixing and grinding the first compound carrier and hydrated sodium hypophosphite for one-hour reaction, and washing and drying the reactant to obtain a second compound carrier; dispersing the second compound carrier in glycol, adding hexachloropalladate, and performing ultrasonic dispersing and stirring to obtain a first turbid liquid; stirring the first turbid liquid at the room temperature, and regulating the pH value with sodium hydroxide to obtain a second turbid liquid; performing microwave radiation on the second turbid liquid, and obtaining a supported palladium catalyst. The palladium-based catalyst prepared by the method has extremely high catalytic activity and relatively high stability to formic acid electro-oxidation. Meanwhile, the capacity of the precious metal palladium can be reduced, and the method is simple to operate, short in preparation period and suitable for mass production.
