Application of micro-nano functional materials in environmental governance

This reviews introduces various types of adsorption materials for air and water pollution treatment, and elaborates the latest research progress on enhanced enrichment/catalytic degradation integrated composites in environmental governance. Through comparison, although the adsorption materials are cheap, stable and easy to operate, and it has good adsorption performance for waste water and exhaust gas, and the adsorption capacity can be further improved by certain modification methods. However, it has been limited due to the low adsorption capacity, extremely easy to saturate, frequent material replacement, and easy to cause secondary pollution after adsorption saturation. Catalytic technology is the catalytic oxidation of these pollutants into small inorganic molecules such as CO2 and H2O, which is cheap, no secondary pollution, high purification rate, and low energy consumption. Combining adsorption with catalytic technology, it can be found that the addition of adsorption materials has successfully improved the catalytic efficiency of the catalyst, which can solve the disadvantages of adsorption technology while retaining the advantages of catalytic technology. It is one of the most promising methods to deal with these pollutants. © 2020, Chemical Industry Press. All right reserved.
