Utilization of carbon dioxide (CO2) is a huge challenge for global sustainable development. Biological carbon fixation occurs in nature, but the low energy efficiency and slow speed hamper its commercialization. Physical-chemical carbon fixation is efficient, but relies on high energy consumption and often generates unwanted by-products. Combining the advantages of biological, physical and chemical technologies for efficient utilization of CO2 remains to be an urgent scientific and technological challenge to be addressed. Here, based on the development of Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences in the past decade, we summarize the important progress in the design and construction of functional parts, pathways and systems for artificial bioconversion of carbon dioxide, including the breakthrough on the artificial synthesis of starch from CO2. Moreover, we prospect how to further develop the technologies for artificial bioconversion of carbon dioxide. These progress and perspectives provide new insight for achieving the goal of "carbon peaking and carbon neutrality".
