Outline of Final Research Achievements

In this study, we developed scalable synthesis processing of well-controlled chalcogenide nanosheets catalyst by using supercritical fluid. As a result, we achieved fast synthesis of agglomerates of Mo(S,Se)2 nanosheets with edge-exposed structure by the assistance of reductive agents in supercritical ethanol. The layer-number-controlled and S/Se-ratio-controlled Mo(S,Se)2 catalyst exhibited excellent performance for hydrogen evolution reaction.
