| Research Abstract |
Tetrahedrally Coordinated Metal Oxides Assembled Catalysts was designed by a stepwise chemical vapor deposition (CVD) method using metal chlorides, organometallic complexes and metal alkoxides as building blocks. Characterizations by XAFS, UV-vis, photoluminescence measurements showed that the metal oxides in these catalysts existed in the highly dispersed state at the atomic level on the surface of catalyst supports. The comparative studies using single component catalyst as reference revealed that these assembled catalysts have unique and higher photocatalytic performances in various reactions such as CO oxidation and polymerization of ethylene under UV and visible light.
