A short channel ordered mesoporous carbon loaded indium cobalt sulfide and indium nickel sulfide ternary composite photocatalyst, and a preparation method and application thereof. The short channel ordered mesoporous carbon loaded indium cobalt sulfide and indium nickel sulfide ternary composite photocatalyst is prepared by mixing pretreated short channel mesoporous carbon with cobalt salt, nickel salt, indium salt and reducing agent with a hydrothermal reaction. The short channel ordered mesoporous carbon is obtained by calcining a short channel ordered mesoporous silica and a carbon source under the protection of nitrogen, wherein the short channel ordered mesoporous silica is prepared by carrying out reactions of sol-gel-hydrothermal-calcination sequentially using a mixture of a surfactant, a hydrochloric acid solution, ammonium fluoride and tetraethyl orthosilicate. The photocatalyst has strong adsorption and visible light catalytic activity on VOCs, and can effectively adsorb and decompose the enriched VOCs in situ on the surface of the catalyst. |
