Cobaloxime‐Based Photocatalytic Devices for Hydrogen Production

Abstract

It is the dawning of the age of supramolecular photocatalysts for H2 production using first-row transition-metal catalytic centers. These catalysts consist of a ruthenium tris(diimine) light-harvesting unit covalently linked to various catalytic cobaloxime centers (see picture). The catalyst stability, CoII/CoI redox potential, and nucleophilicity of the cobaloxime moiety all affect the photocatalytic properties.
