Research Progress of Kaolin-Based Catalysts in Environmental Pollution Purification
Kaolin is a natural layered aluminosilicate clay mineral that was widely used in the traditional fields of ceramics production,papermaking industry and fireproofing materials.Recently,it was found that the kaolin could be served as the clean carriers to support environmental catalysts for their advantages of friendly environment,facile modification and low price.In this review,the scientific and technical literatures related to kaolin-based catalytic materials published in the past ten years were investigated,which were classified as TiO2,ZnO,C3N4,metal simple substance,metal oxide,Fenton catalysts and natural enzymes supported on kaolin carriers.The preparation,characterization and comprehensive performance of these representative kaolin-based composites were summarized,and their purification and treatment effectiveness of various environmental pollutants are comprehensively evaluated.Moreover,the future development of environmental catalysis of kaolin-based catalytic composites was prospected.
