▎ 摘  要

NOVELTY - Preparing catalyst based on titanium nitride and nitrogen-doped composite graphene-black phosphorus, comprises (i) mixing 0.1-0.2 g graphene oxide and 0.1-0.2 g black phosphorus uniformly, dispersing in 10 ml absolute ethanol, and drying to obtain composite graphene-black phosphorus powder, (ii) dispersing graphene-black phosphorus powder and 2-3 ml tetrabutyl titanate in 15 ml absolute ethanol respectively, mixing the obtained two dispersions and continue to stirring overnight to obtain a reducing agent dispersion, (iii) preparing reducing agent powder, filtering and separating the reducing agent dispersion liquid, cleaning and drying to obtain reducing agent powder, and (iv) preparing catalyst based on titanium nitride and nitrogen-doped composite graphene-black phosphorus, and calcining. USE - The catalyst is useful for preparing hydrogen by electrolyzing water (claimed). ADVANTAGE - The catalyst has very high catalytic activity, can catalyze ORR to proceed in a path close to four-electron transfer, and is a promising fuel cell cathode ORR electrocatalyst. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for catalyst based on titanium nitride and nitrogen-doped composite graphene-black phosphorus prepared according to above mentioned method.
