Preparation method of catalyst for electro-catalytic degradation of phenolic environmental pollutants

Abstract

A phenolic compound is a compound generated by substituting a hydrogen atom on a benzene ring in aromatic hydrocarbon with a hydroxyl group, and can be divided into monohydric phenol and polyhydric phenol according to the number of hydroxyl groups contained in the molecule. Catalytic degradation of phenolic pollutants is a hotspot problem in the field of environmental catalytic chemistry, and electro-catalytic degradation of phenolic pollutants has important scientific and practical significance for evaluating environmental ecology. Pollution caused by phenolic organic pollutants in a water body can pollute the atmosphere, water, soil and food if the phenolic organic pollutants are directly discharged and irrigated in a farmland without being treated, and the ecological environment and thelife safety of people are seriously harmed. The electro-catalytic degradation of the phenolic organic pollutants is used in the electro-catalytic process, so that the degradation of the phenolic organic pollutants is realized, and a new thought is provided for constructing an environment-friendly society.

Description

technical field [0001] The present invention relates to the preparation method and application field of a catalyst doped with various nonmetals, in particular to a method for preparing C, P-MoO 3 The method of nanosheet catalyst and its application in the field of electrocatalytic degradation of phenolic environmental pollutants. Background technique [0002] Hydroxyl-containing derivatives of aromatic hydrocarbons are divided into volatile phenols and non-volatile phenols according to their volatility. Most of the phenolic compounds that exist in nature are the result of plant life activities. The phenols contained in plants are called endogenous phenols, and the rest are called exogenous phenols. Phenolic compounds have a special aromatic smell, are weakly acidic, and are easily oxidized in the environment. The content of phenol and cresol is the highest in phenolic wastewater. Therefore, volatile phenols such as phenol and cresol are often used as pollution indicators i...

Problems solved by technology

The traditional single catalyst faces problems such as low catalytic efficiency and poor catalytic effect. Therefore, the development of highly efficient doped catalysts has important guiding significance for the field of catalysis. Single doping does not improve the performance of catalysts significantly, so the development of multi-doped Heterocatalysts are imperative
