OPTIMIZATION OF PARAMETERS IN HEAT-TREATMENT OF PORPHYRIN CARBON CATALYST OF OXYGEN-ELECTRODE

A porphyrin-carbon catalyst has been investigated to determine how its electrochemical activity and catalytic properties are influenced by t he temperature at which the cobalt tetramethoxyphenylporphyrin is trea ted, the size of the CoT(p-OCH3)PP particles, and the content of the p orphyrin on acetylene black. It has been shown that the optimal effect of heat treating on the electrocatalytic properties is achieved when the CoT(p-OCH3)PP is deposited in molecular form by adsorption from so lution. The processes taking place heat treating CoT(p-OCH3)PP in a mi xture with acetylene black have been investigated by means of thermogr avimetric and differential thermal analysis, and also by spectroscopic methods.
