Paper Title:
Photocatalyses of Nano-Scaled ZnSe/TiO2 and ZnS/TiO2 Heterojunctions
  Abstract

High quality nano-scaled fluorine and nitrogen co-doped anatase phase TiO2 can be obtained from the conversion of ammonium oxotrifluorotitanate by thermal treatment. The photocatalytic activity of TiO2 treated at 800oC shows the highest photocatalytic activity and is about 1.3 times of commercial P-25. The heterojunctions of ZnSe/TiO2 and ZnS/TiO2 prepared by metal organic vapor phase epitaxy shows 2.0 and 1.5 times the photocatalytic activities of commercial P-25. In this study, nano-scaled TiO2, ZnSe/TiO2 and ZnS/TiO2 heterojunctions show one to one correspondence between carrier lifetime and photocatalytic activity.
