Abstract

The invention belongs to the technical field of material preparation and photocatalysis, and particularly relates to an MMoS4 / g-C3N4 (M is equal to Co, Ni, Cu) composite photocatalytic material, and apreparation method and application thereof. MMoS4 particles are loaded on graphite phase carbon nitride through a coprecipitation method so as to form the composite photocatalytic material; the preparation method has the advantages of simple and convenient preparation process, low coat, and easy large-scale industrial production; the prepared composite photocatalytic material has a heterojunctionstructure formed by compounding ternary metal sulfide and g-C3N4, so that the separation of a photon-generated carrier is greatly promoted, a surface hydrogen production dynamic behavior is improved,the hydrogen production activity of a photocatalyst is remarkably improved, and the photocatalytic material has favorable environmental stability and can be applied to visible light photocatalysis hydrogen production in an alcohol-water system.

Description

technical field [0001] The invention belongs to the technical field of material preparation and photocatalysis, and specifically relates to MMoS 4 / g -C 3 N 4 (M=Co, Ni, Cu) composite photocatalytic materials and their preparation methods and applications in photocatalytic hydrogen production. Background technique [0002] Fossil fuels are non-renewable energy sources, and the problems of global warming and environmental pollution caused by the carbon dioxide gas released from the combustion of fossil fuels also follow. Therefore, exploring clean and environmentally friendly sustainable energy has attracted extensive attention. Since solar energy is an inexhaustible and inexhaustible renewable energy source, the direct conversion from solar energy to hydrogen energy by using photocatalytic water splitting to produce hydrogen is one of the ideal ways to obtain new energy. [0003] So far, hundreds of semiconductor photocatalysts with the activity of splitting water to pro...
