Anode catalyst for water electrolysis hydrogen production by taking transition metal doped titanium oxide as a carrier and preparation method of anode catalyst

The invention discloses an anode catalyst for water electrolysis hydrogen production by taking transition metal doped titanium oxide as a carrier and a preparation method and application of the anodecatalyst. Stable, conductive and high-specific-surface-area porous transition metal doped titanium oxide is selected as a carrier of precious metal oxide nanoparticles. The catalyst prepared by combining the nanocrystallized noble metal material can greatly improve the dispersity of active noble metal and the density of surface active sites so that the utilization rate and the mass specific activity of the precious metal are improved, and the oxygen evolution mass specific activity can reach 7-8 times of that of commercial iridium oxide while the loading capacity of the precious metal in the membrane electrode of the water electrolyzer is reduced. 本发明公开了一种以过渡金属掺杂氧化钛为载体的水电解制氢用阳极催化剂及其制备方法和应用，选用稳定、导电、高比表面积的多孔过渡金属掺杂氧化钛为贵金属氧化物纳米颗粒的载体，结合纳米化的贵金属材料制备的催化剂能大大提高活性贵金属分散性和表面活性位点密度，从而提高贵金属的利用率和质量比活性，进而使析氧质量比活性可达到商业铱氧化物的7-8倍的同时减
