The Character of photo-electrochemistry of Palladium Implanted TiO_2 Nano-crystalline Electrode

Chinese Chemical Letters 2001年第1期12卷 73-74页

作者： Cun Zhong ZHANG Jing YANG Zhong Da WU Sheng Min CAI En Qin GAO Department of Chemistry Beijing Normal UniversityBeijing 100875 Department of Chemistry Peking UniversityBeijing 100871

A new electrode was prepared by using Pd implanted into nano-crystalline TiO2 and the character of photo-electrochemistry of implanted electrodes was investigated. The energy band structure of nano-crystalline TiO2 has not changed after implantation with Pd. The photo-current (i(ph)) of palladium implanted TiO2 nano-crystalline electrode is larger than that of pure TiO2 nanocrystalline electrode.

Carbon and nitrogen species-involved TiO2 （CN-TiO2） were systematically synthesized by thermal condensa- tion of cyanuric acid on the TiO2 surface. And the photocatalytic reactions for H2 production from sacrificial aque- ous solutions were performed on several CN-TiO2 photocatalyst under visible-light irradiation. The photocatalytic activity of the CN-TiO2 was influenced by total amounts of carbon and nitrogen species, and the preferable activity was ten times higher than that of pristine carbon nitride. Here, the states of the CN-TiO2 photocatalyst were charac- terized by XPS, FT-IR and UV-Vis spectroscopy as well as DFT calculations. The photo-electrochemical measure- ments confirmed that the enhancement of H2 production is associated with effective charge separation under photo- excitation of highly dispersed carbon nitride on the TiO2 surface.
