Abstract

Samples of iron naphthalocyanine (FeNPc) have been synthesized on carbon black and on active charcoal (ex-CH4 and Norit BrX). These samples were examined by RDE and voltammetric techniques. After prolonged contact with acids, the samples were also investigated by XPS. The impregnations on Norit proved to be stable in H2SO4 solutions, whereas the ex-CH4 samples were stable only in HC1O4 solution. The XPS data indicated that in catalytically active samples the in situ synthesized FeNPc molecules are deformed. The activity of FeNPc on Norit BrX remains higher than on ex-CH4, despite considerable demetallation.
