| Outline of Final Research Achievements |
Protein(peptide) can be regarded as one of biomass-derived key materials, and can be obtained from green biomass. Therefore, development of transformation methods of protein is required. Dissociation of the amide bonds is one strategy for that, however, the methods that use stoichiometric amount of acids or bases are used as main ones, and alternative environmentally-benign methods are required. In this study, we investigated heterogeneous catalysts that enables direct cleavage of C-N bond in amide by hydrogenation, and found that N2-treated Ru/CeO2 catalyst showed high activity and selectivity for the reaction and that the small Ru particles over Ru/CeO2 are responsible active species for the high performance.
