| titleOfInvention | Efficient hydrogen evolution catalyst material, preparation method and application |
| abstract | The invention relates to a preparation method of a high-efficiency hydrogen evolution catalyst material, which comprises the following steps: 1) preparation of palladium ammonium complex: adding palladium chloride and ethylenediamine into deionized water for ultrasonic treatment; 2) dispersing ammonium tetrathiomolybdate and urea in N, N-dimethylformamide to form a homogeneous solution; transferring the palladium-ammonium complex into the solution, carrying out ultrasonic treatment, adding hydrazine hydrate, and continuing ultrasonic treatment; 3) adding the obtained solution into a reaction kettle and reacting for 4 hours at the temperature of 160-; 4) and after the reaction is finished, naturally cooling to room temperature, carrying out solid-liquid separation, washing and drying the precipitate, and calcining the obtained sample at 400 ℃ for 2h in a hydrogen environment to obtain the material. The high-efficiency hydrogen evolution catalyst material can obviously improve the Hydrogen Evolution (HER) performance of the catalyst. |
