Biocoupled Catalytic Systems for CO 2 Conversion

Anthropogenic excess CO2 emissions, which come primarily from fossil fuel combustion and industrial processes, are unequivocally linked to global warming, manifested in rising sea levels, intensified extreme weather events, and irreversible ecosystem disruptions. Converting CO2 into useful compounds is an effective strategy for solving these problems. Biocatalysis or chemocatalysis presents a strategy for addressing CO2 conversion challenges, yet achieving efficient synthesis of carbon-rich, high-value chemicals remains a critical hurdle. Biocatalysis, distinguished by its ambient reaction conditions and exquisite selectivity, offers advantages for coupling with chemocatalysis, photocatalysis, or electrocatalysis into biocoupled catalytic systems. Biocoupled catalytic systems facilitate CO2 conversion into multicarbon compounds, significantly enhancing carbon value addition. This review systematically summarizes recent breakthroughs in biocoupled catalytic systems, emphasizing reaction pathways and product diversity. Finally, we provide future perspectives to inspire multidisciplinary innovations for achieving carbon neutrality through next-generation catalytic technologies.
