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

In recent years, organic Carbon Nanotubes (CNTs) have attracted wide attention because of their excellent and unique properties 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 photo-catalytic performance. It was found that the surface modification of metal-composite photocatalyst using organic carbon nanotubes could effectively improve the photo-catalytic activity and stability of metalcomposite photocatalyst materials. This paper aims to provide the current research progress of organic carbon nanotubes-modified metal-composite photo-catalytic materials in water pollution control, including the preparation methods of organic carbon nanotubes and their modified metal-composite photocatalysis materials, as well as the applications of organic carbon nanotubes-modified metalcomposite photocatalytic materials in water pollution control field. Concluding remarks and future trends are also pointed out. This paper can provide guidance for designing high-performance carbon nanotube metal-composite photo-catalytic materials.
