Preparation method of catalyst for electro-catalytic production of hydrogen peroxide as well as product and application of catalyst

The invention discloses a preparation method of a catalyst for electrocatalytic production of hydrogen peroxide and a product and application of the catalyst. Tungsten carbide is used as a modified precursor, carbon dioxide is doped with oxygen at high temperature, and a specific oxygen-containing functional group is introduced on the surface of the tungsten carbide; the transition metal carbide is used as a precursor, the transition metal carbide is subjected to surface modification to be combined with transition metal and oxygen-containing functional groups, the materials are compared through different treatment methods, and the catalyst with the optimal performance is obtained on the basis of a large number of experiments. 本发明公开了一种电催化生产过氧化氢的催化剂的制备方法及其产品和应用，以碳化钨作为改性前驱体，利用二氧化碳高温掺氧，在碳化钨表面引入特定的含氧官能团，本发明使用过渡金属碳化物作为前驱体通过对其进行表面改性来结合过渡金属及含氧官能团，采用了不同的处理方法对材料进行对比，在大量的实验的基础上得到了性能最优的催化剂。
