摘要：

The heat treatment of iron tetraphenylphorphyrin chemically modified glassy carbon electrode is described. This electrode shows high catalytic activity and good stability for dioxygen reduction. Its catalytic activity is still maintained through 1000 cycles of potential scans (100 mv/s)in an air saturated solution of 0. 05 M H//2SO//4 after a heat treatment to 500 degree C. Using XPS, Mossbauer, UV-VIS spectroscopy and mass spectroscopy the microstructure of the electrode surface has been analyzed. The electrocatalytic and dynamic behavior for dioxygen reduction has been studied by cyclic voltammetry and rotating disk electrode respectively.
