利用太阳能驱动二氧化碳（CO₂）转化有利于节能减排、缓解温室效应和解决能源短缺问题，为构建可持续发展的社会提供了光明的前景，但目前仍存在二氧化碳转化率较低、产物选择性较差等问题。文章综述了当前研究较为热门的光催 化转化、光热转化、光电协同转化和生物技术转化的反应原理、基本步骤以及催化剂类型，重点介绍了在提高二氧化碳转 化效率和反应选择性方面进行的催化剂改良、生物转化途径改进，最后对未来太阳能驱动二氧化碳转化技术进行了展望。

Carbon dioxide conversion by solar energy relieves the pressure from both the carbon dioxide emission and energy demand, which brings a bright future for sustainable society construction. However, the drawback of carbon dioxide conversion by solar energy was its low efficiency and low specificity. The authors summarized the principles, procedures, and catalysts involved in state-of-the-art progress of carbon dioxide conversion, including photocatalysis, solar-thermal catalysis, photoelectric catalysis, and biotechnological conversion. It was emphasized the on-going research about catalysts modification and biotechnological conversion to improve the efficiency of carbon dioxide conversion, and reaction specificity. Finally, an outlook was provided for carbon dioxide conversion by solar energy for future development.
