Our research will be guided by the motto of “Novelty + Application = Admirable”. We will focus on the development of highly efficient homogenous catalytic system for dehydrogenation and hydrogenation in three research directions: oxidant-free transition-metal-catalyzed cross coupling reaction via hydrogen release; non-precious transition-metal-catalyzed hydrogenation in biomass transformation; photo‐and transition metal catalyzed H2 generation from H₂O without sacrificial electro donors. They are closely related and promote each other.
