摘要
半导体光催化作为一种绿色催化技术,具有广阔的应用前景。然而,到目前为止,光催化材料仍存在可见光利用率低,稳定性差,催化效率较低,难回收等问题。其中,光催化剂的负载化是解决回收与再利用的关键,也是其走向绿色应用的必由之路。蒙脱石是一种由颗粒极细的含水铝硅酸盐构成的层状矿物,在自然界中储量大、开采成本低,是一种优良的载体材料,在光催化材料中得到了广泛应用。本文系统介绍了目前蒙脱石基复合光催化材料的研究进展及其制备工艺,讨论了光催化技术在现实中的主要应用,最后对其发展前景进行了展望。
As a green catalytic technology, semiconductor photocatalysis has widely application prospects. However, so far, photocatalytic materials still have some problems, such as low visible light utilization rate, poor stability, low catalytic efficiency, difficult recovery and so on. Among above problems, the loading of photocatalyst is the key to solve the problem of recovery and reuse which also is the only way to its green application. Montmorillonite, as a kind of layered mineral composed of extremely fine hydrous aluminosilicate, is a good carrier material due to its large reserves and low mining cost in nature and has been widely used in photocatalytic materials. In this paper, the research progress of montmorillonite-based composite materials was systematically reviewed. The main preparation processes of montmorillonite-based composite photocatalytic materials were introduced. The main applications of photocatalytic technology in reality were discussed. Finally, the development of montmorillonite-based composite photocatalytic materials was prospected.
