Rhodium porphyrin complexes deposited on carbon support exhibit high activity for electrochemical CO oxidation. As such, they are good candidates for CO-tolerant catalysts in polymer electrolyte fuel cells. For the practical use of rhodium porphyrin complexes, however, their stability in water is of paramount importance. In this study, rhodium (III) octaethylporphyrin chloride was deposited on a highly oriented pyrolytic graphite substrate and observed by atomic force microscopy before and after water treatment. Although treatment with water changed the surface structure of RhOEP/HOPG, the face-on RhOEP layer remained intact. [DOI: 10.1380/ejssnt.2018.253]
