Abstract

The invention relates to the field of environmental protection, and discloses a low-energy chemical field-driven organic pollutant degradation catalyst and an application thereof. The catalyst can efficiently degrade azo dyes, nitro compounds and various other organic pollutants without providing additional energy. The catalysis system uses formate as an assistant, metallic palladium, silver, gold, platinum and iridium are used as catalytic active main bodies and are supported on the surface of a carrier oxide, C-H bonds in formate radicals are broken when the formate ions in a mixed solutionof the formate and organic pollutants are in contact with a transitional noble metal interface in order to form reactive oxygen species, the reactive oxygen species include hydroxyl radicals, hydrogenperoxide radicals, carbonate radicals and the like, and the generated free radicals rapidly oxidize adsorbed organic matters into small-molecular substances which can be naturally degraded, or even nontoxic water, CO2 or carbonates. The catalyst has the advantages of extremely high efficiency in organic pollutant degradation treatment, low cost, stable catalysis system and high recycling rate.

Description

technical field

[0001] The invention relates to the field of environmental protection, in particular to a catalyst for degrading organic pollutants driven by a low-energy chemical field and an application thereof. Background technique

[0002] The environment is the basic prerequisite for human survival and development. With the rapid development of economy and continuous progress of society, the ecological environment on which human beings rely is increasingly polluted and destroyed. Protect the environment, reduce environmental pollution, and develop low-energy and efficient environmental governance technology. Water pollution is one of the three pollutions, among which organic pollution (printing and dyeing wastewater, pesticides, antibiotics, detergents, etc.) is of great significance to explore and develop low-cost and efficient methods for degrading organic pollutants in water due to its large content and high concentration .

[0003] At present, there are mainly t...
