摘要
光催化技术在解决环境污染和能源短缺问题方面表现出了独特的潜在应用价值。然而半导体光催化剂在实际应用中容易出现颗粒团聚、不易分离回收等问题。将光催化剂负载到载体上可以有效地避免团聚问题,同时能够增强催化剂的光催化活性和稳定性。系统综述了高岭土作为光催化剂载体的研究进展,讨论了高岭土基光催化剂的制备方法及其在光催化方面的应用,阐述了高岭土基复合材料的催化机制,并对高岭土未来应用于光催化领域的研究方向进行了展望。
In the past decades,semiconductor photocatalysis have attracted worldwide interest owing to its potential application in solving environmental pollution and energy shortage.Nevertheless,semiconductor photocatalysts are tended to agglomerate,and difficult to separate and recover in practical application.Loading photocatalysts on certain supporters can effectively avoid the problem of agglomeration,and enhance their photocatalytic performance and stability.The research progress of kaolin-based composites in the photocatalytic field was systematically reviewed.The preparation method of kaolin-based photocatalysts and its application in the photocatalytic field were discussed.In addition,the catalytic mechanism of the kaolin-based composites was elaborated.Finally,the prospects of the future application of kaolin-based photocatalysts were given.
