Outline of Final Research Achievements

In this work, we tried to develop highly active and robust molecular catalysts for hydrogen evolution from water. We also attempted to elucidate the reaction mechanism of those catalysts. Consequently, we successfully demonstrated that some cobalt, platinum and nickel complexes serve as highly active molecular catalysts for hydrogen evolution from water, where the molecular nickel catalyst shows high robustness. Furthermore, we could gain several mechanistic insights, as we found that these catalysts proceed hydrogen evolution via ligand- or metal-centered proton-coupled electron transfer pathway.
