Problems solved by technology

In recent years, more research tends to study carbon-based material-supported metal oxide catalysts. These catalysts are generally concentrated in the treatment of air pollution and water pollution, and their preparation processes are mostly impregnated with soluble metal salts. Carbon-based materials, etc. , and impregnation with a single metal salt or multiple metal salts cannot form a superior crystal structure, so the efficiency is not very high

Abstract

The invention discloses a novel carbon-based material supporting spinel catalyst and a preparation method thereof, wherein a carbon-based substance serves as a supporter and transition metal elements, in a spinel or an inverse spinel structure, are supported on the supporter through the steps of stepwise impregnation, alkali treatment, high-pressure hydrolysis and the like. According to the method, the spinel can be supported on the carbon-based material, thus producing the carbon-based material supporting spinel catalyst.

Description

technical field [0001] The invention belongs to the field of material preparation and pollution treatment, and in particular relates to a novel carbon-based material-loaded spinel catalyst and its preparation method and application. Background technique [0002] Since the beginning of the 21st century, with the rapid development of China's industry, pollution problems have become increasingly serious. Faced with increasingly stringent national regulations and people's growing awareness of environmental protection, pollution treatment is imminent. The transition metal spinel structure, because of its high ability to transfer electrons, can better promote the oxidation or reduction of pollutants in pollutant treatment, so it is widely used in water pollution or air pollution treatment, but spinel The preparation of stone structure generally adopts the method of solid solution, which consumes a lot of energy, and the purity of the prepared material is not high, and the phase is...
