二氧化碳还原反应中不同催化技术的研究进展

    Research Progress on Different Catalytic Techniques for Carbon Dioxide Reduction Reaction

    • 摘要: 二氧化碳(CO2)作为典型的温室气体,其含量升高是造成全球温室效应的主要因素。随着我国“2030年实现碳达峰”与“2060年实现碳中和”目标的提出,如何实现CO2高效转化成为了我国科研人员关注的重要研究方向之一。二氧化碳还原反应(CO2RR)是利用光催化、热催化、电催化以及生物催化等技术将CO2转化为碳基燃料和高附加值产物的常用手段。然而,上述技术仍存在CO2转化效率低、目标产物选择性低以及反应稳定性差等问题。根据不同催化技术的反应原理,结合催化剂的材料或负载方式等特点,综述了二氧化碳还原生成甲醇、甲烷和乙烯等产物的最新研究进展,为二氧化碳还原和利用提供进一步的参考。

       

      Abstract: Elevated levels of carbon dioxide (CO2), a typical greenhouse gas, are a major contributor to the global greenhouse effect. With China’s goals of “achieving carbon peak by 2030” and “achieving carbon neutrality by 2060”, how to efficiently convert CO2 has become an important research direction for Chinese researchers. Carbon dioxide reduction reaction (CO2RR) is a common means of converting CO2 into carbon-based fuels and high-value-added products using photocatalytic, thermal catalytic, electrocatalytic, and biocatalytic technologies. However, the above technologies still suffer from low CO2 conversion efficiency, low target product selectivity, and poor reaction stability. This paper is based on the reaction principles of different catalytic techniques, combined with the characteristics of the catalysts such as material or loading method. Recent research progress in the formation of products such as methanol, methane, and ethylene from carbon dioxide reduction is reviewed. The aim is to provide further guidance for carbon dioxide reduction and utilization.
