METAL OXIDE-CARBON NITRIDE COMPOSITE MATERIAL AND PREPARATION METHOD AND USE THEREOF

摘要

Provided are a metal oxide-carbon nitride composite material and a preparation method and use thereof. The composite material consists of carbon nitride and a composite metal oxide uniformly dispersed on its surface, and the mass ratio of the carbon nitride to the composite metal oxide is 10-200 : 1. The preparation method has a simple process, and mild reaction conditions. The catalytic performance of the composite material can be optimized by adjusting the ratio between the composite metal oxide and the carbon nitride. The composite material can catalyze H2O and O2 to cleanly produce H2O2 at normal temperature and normal pressure, and the concentration of H2O2 is high.
