Abstract:

Photocatalytic CO2 reduction is a major part of the study of artificial photosynthesis. The conversion of molecule CO2 into fuels, precursor to fuels, or value-added chemicals through visible light induced photocatalysis is considered as an ideal way of fixation and resource utilization of CO2. Metal complexes as molecular catalysts for CO2 reduction had long been used in photocatalytic CO2 reduction systems for its tunable structure, rich valences of contained metal, easy synthesis, and economic advantages. The study of utilization of cobalt complexes as catalysts for photocatalytic CO2 reduction dates from 1980s. A large number of cobalt complexes of Co-macrocycles, Co-porphyrin and its analogues, Co-polypyridine complexes had been developed as catalysts to mediate CO2-CO or CO2-formate conversion in particular photocatalytic CO2 reduction systems. Herein, we review the development and advances of the study on molecular systems for photocatalytic CO2 reduction based on cobalt complexes as catalysts. The cobalt complexes used in photocatalytic CO2 reduction systems are classified and discussed. The structures, mechanisms, and composition of systems are reviewed. In the end of the review, a summary and outlook are given.
