Abstract: CO₂ is not only the most important greenhouse gas but also an important resource of elemental carbon and oxygen. From the perspective of resource and energy strategy, the conversion of CO₂ to chemicals driven by renewable energy is of significance, since it can not only reduce carbon emission by the utilization of CO₂ as feedstock but also store low-grade renewable energy as high energy density chemical energy. Although studies on photoelectrocatalytic reduction of CO₂ using renewable energy are increasing, artificial bioconversion of CO₂ as an important novel pathway to synthesize chemicals has attracted more and more attention. By simulating the natural photosynthesis process of plants and microorganisms, the artificial bioconversion of CO₂ can efficiently synthesize chemicals via a designed and constructed artificial photosynthesis system. This review focuses on the recent advancements in artificial bioreduction of CO₂, including the key techniques, and artificial biosynthesis of compounds with different carbon numbers. On the basis of the aforementioned discussions, we present the prospects for further development of artificial bioconversion of CO₂ to chemicals.
