Progress in photo-enzyme coupling catalysis for carbon dioxide reduction

By mimicking natural photosynthesis, the photo-enzyme coupling catalysis (PECC) for carbon dioxide conversion integrates the advantages of photocatalysis and enzymatic catalysis, offering an effective and innovative pathway for capture and utilization of greenhouse gas. This review provides a comprehensive overview of recent advancements in this technology, covering the fundamental principles, key components, synergistic mechanisms, compatibility, and future perspectives. A photo-enzyme coupling system (PECS) can be categorized into cofactor-dependent or cofactor-independent system based on the requirement for cofactor mediation. Its main components include photocatalyst and enzyme, which demonstrates unique advantage in the synergism of energy transfer and substrate activation. In order to improve the compatibility of PECS, the strategies including compartmentalized immobilization and process optimization are employed. By developing highly efficient photocatalyst, strengthening interfacial interaction, and optimizing enzyme engineering, PECC holds great promise for transitioning from laboratory research to industrial application, providing robust support for mitigating global climate change and addressing energy crisis.
