摘　　要：有机污染物在环境中的大量残留对人类健康和生态环境造成严重威胁。催化反应技术具有反应迅速、氧化性强等优势,被认为是环境污染物治理十分有效的方法之一。天然黏土矿物具有微观形貌多样、表面基团丰富和成本低廉等优势,作为功能性催化剂载体材料显示出巨大的应用潜力。基于此,本文介绍了高岭石、蒙脱石、累托石、埃洛石、坡缕石等不同黏土矿物与活性组分之间的相互作用,有针对性地对黏土矿物进行功能化改性,开发适合解决环境污染问题的高性能催化材料,阐明了黏土矿物基催化材料的催化机理。最后,本文总结了黏土矿物在催化研究中的一些问题,对构建低成本、高性能黏土基催化材料高效降解污染物体系具有重要的理论指导和实际价值。Nowadays, the excessive pollutants have been a serious problem, which poses a threat to human health and ecological environment. Catalytic technology is considered to be one of the most effective methods to degrade pollutants considering its advantages of rapid reaction and strong oxidation. Natural clay mineral possesses a series of advantages including excellent structure, physicochemical property, aplenty of hydroxyl groups and low cost, which could be applied to support materials of catalyst. In this review, we discuss the interaction between different clay mineral and active component and carry out to develop high-performance catalytic materials for solving environmental problems. In addition, the catalytic mechanism of clay mineral materials is also explained clearly. Based on the summarized problems of clay mineral in catalytic research, our work will be of remarkable theoretical significance and practical values in preparing the clay-based catalytic catalysts in pollutant degradation and environmental remediation.
