Abstract

Ti02 films were cheap，non-toxic，stable，easily to use and had the advantages of recycling．It had a very wide range of application in the field of environmental pollution control and photoelectric conversion．At present，Ti02 films have entered a practical stage， but there are still many technical problems of low photocatalytic activity and low utilization of sunlight and Ti02 films photoelectric conversion technology is still in the experimental stage．In recent years，technology of Ti02 films has a rapid development，including precious metals deposition，transition metal ion dopin易the non-metallic doped photosensitive surface and the methods of compound semiconductor．In this paper,the new material Multi-walled carbon nanotubes(MWNTs)was added to Ti02 and it was successful t
