摘　　要：CO_(2)作为一种主要的温室气体,大量排放引发的环境问题已引起全球关注。将CO_(2)通过物理或化学方法转化成具有高附加值的碳材料、化学品及燃料是近年来研究的重点之一。综述了CO_(2)的主要转换方法,详细阐述了电催化、光催化和热催化CO_(2)的原理和催化剂的选择方法。其中电催化和光催化能够在较低的温度和压力下进行反应,但转化率较低,产物选择性不理想,反应装置复杂,制约了工业化发展;热催化转化方法反应器设计简单、生产效率高,易于产业化推广,但受到化学动力学或热力学平衡的限制,转化率受到一定的制约。研发和制备转化效率高、稳定性好的新型催化剂是未来的发展方向之一,为CO_(2)的转化和综合利用提供方法和借鉴。Carbon dioxide,as a greenhouse gas,has caused a series of problems due to its massive emissions.However,at the same time,carbon dioxide is also an abundant,inexpensive,and easily accessible carbon resource.Therefore,converting carbon dioxide into high-value carbon materials,chemicals,and fuels through physical or chemical methods has become one of the research focuses in recent years.The article summarizes the main conversion methods of carbon dioxide and elaborates on the principles of electrocatalysis,photocatalysis,and thermal catalysis of carbon dioxide,as well as the selection methods of catalysts.Although electrocatalysis and photocatalysis can react at lower temperatures and pressures,their conversion rates are low,product selectivity is not ideal,and the reaction equipment is complex,which restricts their industrial development.The thermal catalytic conversion method has a simple reactor design,high production efficiency,and is easy to industrialize and promote.However,due to limitations in chemical kinetics or thermodynamic equilibrium,the conversion rate is subject to certain constraints.Therefore,the research and preparation of new catalysts with high conversion efficiency and good stability have become one of the development directions in the future.This article provides methods and references for the conversion and comprehensive utilization of carbon dioxide.
