1 PROGRESS IN CHEMISTRY Vol. 17 No. 4 Jul., ( ) ( ), : O627 ; O : A : X(2005) Research of Metalloporphyrins as Mimic Enzyme Catalysts Wang Lanzhi She Yuanbin 3 Xu Weiwei Zhang Yanhui ( Institute of Green Chemistry, Beijing University of Technology, Beijing , China) Ji Hongbing (School of Chemical and Energy Engineering, South China University of Technology, Guangzhou , China) Abstract The applications and mechanism of metalloporphyrins in catalytic oxidation are discussed. Quantum calculation method used in molecular design, uncovering relation between structure and catalytic activity of metalloporphyrins is reviewed. Recent works of authorsresearch group are also introduced. The future application of metalloporphyrins in catalysis is prospected. Key words metalloporphyrins ; oxidation reaction ; catalysts ; quantum calculation 18 P2450 ; Rothemund [1 ],, h ( TPP),2004,, : , : e2mail : edu. cn
