Heterogeneous Photocatalytic Hydrogenative Reactions Using Liquid Hydrogen Donors: Mechanisms, Catalysts Design, and Applications

Abstract

AbstractHeterogeneous photocatalysis is a promising approach for a wide range of hydrogenative reactions owing to the mild reaction conditions and the possibility of employing liquid hydrogen donors. Currently, the major interest is focused on the development of high performance photocatalyst materials and the expansion of reaction scope. An overview from a perspective of hydrogen donor and thus the related mechanistic understanding of the light‐induced hydrogenative reactions is rare. Here, we have categorized the photocatalytic hydrogenative reactions by the type of employed liquid hydrogen donors (hydrocarbons and water), discussed the basic criteria of hydrogen abstraction from these donors, and elaborated the design strategy of the photocatalyst materials.
