Carbon-supported transitional metal carbon nitride compound as well as preparation and application thereof

Abstract

The invention relates to a charcoal-supported transition metal carbon-nitrogen compound, a preparation method and application thereof. The transition metal compound is supported on a charcoal carrier by adopting a dipping method, and is dried and roasted to obtain a precursor. The prepared precursor is subjected to temperature programmed reaction in mixed gas of ammonia gas and hydrogen gas to obtain the transition metal carbon-nitrogen compound highly dispersed on the charcoal carrier. The charcoal-supported transition metal carbon-nitrogen compound prepared through the method shows good catalytic activity in various hydrogen-involved reactions.

Description

technical field

[0001] The present invention relates to carbon-supported transition metal carbonitrides, and specifically provides a supported transition metal carbonitride with carbon materials as a carrier and a preparation method thereof, as well as the use of such carbonitrides in hydrazine decomposition reactions and other hydrogen-related processes. React application. Background technique

[0002] Transition metal nitrides and carbides are a class of mesenchymal compounds formed by nitrogen or carbon atoms embedded in the lattice of transition metals, and have the properties of covalent solids, ionic crystals, and transition metals at the same time. Since Levy and Boudart reported that tungsten carbide exhibited noble metal-like properties in a series of catalytic reactions in 1973, transition metal nitrides and carbides have attracted great attention as a new class of catalytic materials.

[0003] At present, in the field of catalysis, the synthesis of pure phase and...
