Outline of Final Research Achievements

We analyzed a Rh porphyrin, which exhibits high electrocatalytic activity, on a carbon support by TEM, AFM, and first-principles calculation, and elucidated the distribution/configuration of the molecules. Direct TEM observation of a Rh porphyrin/carbon catalyst revealed the highly dispersed Rh atom on the surface of the carbon support. AFM observation of the Rh porphyrin on HOPG indicates that the molecule can be adsorbed on the support with “face-on” manner, however, the interaction between the molecule and HOPG is not rigid. The results are supported by the first-principles calculation. Based on these findings, we have developed excellent catalysts for the electro-oxidation of CO and glucose using Rh complexes.
