摘要：

The photocatalytic decomposition of several substituted benzyltrimethylsilanes and benzyltrimethylstannanes on band gap irradiated TiO2 powders suspended in acetonitrile causes the deposition of SiR(x) and SiO2 and of SnR(x) and SnO2 respectively, on the photoactive surface. A mechanism consistent with interfacial trapping of a photogenerated electron-hole pair can successfully rationalize the observed kinetics and substituent effects.
