▎ 摘　　要

NOVELTY - Preparing graphene loaded transition metal nitride nano composite material comprises mixing and heating transition metal salt and graphene oxide, and then nitriding. USE - The nitride nano composite material is useful for catalyzing the hydrolysis of hydrogen storage compounds to produce hydrogen (claimed). ADVANTAGE - The material: highly disperses transition metal nitride nanoparticles on graphene oxide, and can be used in the hydrolysis and hydrogen production of different hydrogen storage compounds, e.g. sodium borohydride. The method: introduces non-metallic nitrogen to control the electronic structure of transition metals and prevent their oxidation; can improve the activity and stability of the catalyst, with synergistic effect of various elements; disperses the transition metal nitride, which is loaded on the graphene oxide substrate; completely exposes the catalytic active sites and inhibits the agglomeration and loss of nanoparticles; can improve the stability of material; and can achieve excellent catalytic effects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene-loaded transition metal nitride nano composite material prepared by the above method.
