Abstract
The oxygen electroreduction in acid solutions on electrodes of disperse synthetic diamond powder promoted with cobalt tetra(p-methoxyphenyl)porphyrin or its pyrolysis products is studied. A “floating” gas-diffusion electrode and an RDE of isotropic pyrocarbon are used in experiments; in the latter case, the catalyst is immobilized in a Nafion solution. Two types of diamond, with specific area of 5.8 and 170 m2/g, are used. The results are compared with similar data found for promoted acetylene black. A significant effect of the carbon support on electrocatalytical properties of cobalt porphyrin pyrolyzed on it is found.
