Research Progress of Organic Carbon Nanotubes-Modified Metal- Composite Photocatalytic Materials in Water Treatment

Abstract

In recent years, organic carbon nanotubes (CNTs) have attracted wide attention because of their excellent and unique proper-ties in electrical, optical, mechanical, and other fields, as well as their potential application in the water treatment field. Metal composite photocatalysts generally have the problems of electron-hole recombination, which seriously affect their photocata-lytic performance. It was found that the surface modification of metal composite photocatalyst using organic carbon nano-tubes could effectively improve the photocatalytic activity and stability of metal composite photocatalyst materials. This paper aims to provide the present research progress of organic carbon nanotubes modified metal composite photocatalytic materials in water pollution control, including the preparation methods of organic carbon nanotubes and their modified metal compo-site photocatalysis materials, as well as the applications of organic carbon nanotubes modified metal composite photocatalytic materials in water pollution control field. Concluding remarks and future trends are also pointed out. This paper can provide guidance for the design of high performance carbon nanotube metal composite photocatalytic materials.
