Cobalt Complexes of Polypyridyl Ligands for the Photocatalytic Hydrogen Evolution Reaction


Joliat-Wick, Evelyne; Mosberger, Mathias; Weder, Nicola; Spingler, Bernhard; Probst, Benjamin; Alberto, Roger (2021). Cobalt Complexes of Polypyridyl Ligands for the Photocatalytic Hydrogen Evolution Reaction. Chimia, 75(3):180.

Abstract

The reductive part of artificial photosynthesis, the reduction of protons into H2, is a two electron two proton process. It corresponds basically to the reactions occurring in natural photosystem I. We show in this review a selection of involved processes and components which are mandatory for making this light-driven reaction possible at all. The design and the performances of the water reduction catalysts is a main focus together with the question about electron relays or sacrificial electron donors. It is shown how an original catalyst is developed into better ones and what it needs to move from purely academic homogeneous processes to heterogeneous systems. The importance of detailed mechanistic knowledge obtained from kinetic data is emphasized.
