摘要
通过光催化将二氧化碳转化为化学燃料并加以储存和利用,是解决环境问题和能源短缺的一种有效、环保和可持续的方法。二氧化碳作为一种稳定的氧化产物,仅靠光能进行还原是一项挑战,因此必须使用催化剂。因此,二氧化碳光催化还原技术的关键在于开发有效的光催化剂。本综述以 PCRR(光催化二氧化碳还原反应)的基本原理为基础,详细介绍了 PCRR 过程中的核心问题,包括带隙与催化剂还原性能的关系、光生载流子的有效利用、产物选择性以及产物分析方法。然后,结合上述基本原理,以研究实例的形式回顾了各种光催化剂的最新研究进展。最后,本综述对提高 CO2 光催化活性的有效技术进行了总结和深入分析,并对该领域的未来发展进行了展望。
Recent advances in novel materials for photocatalytic carbon dioxide reduction
The conversion of CO2 into chemical fuels, which can be stored and utilized through photocatalysis, represents an effective, environmentally friendly, and sustainable means to address both environmental concerns and energy shortages. CO2, as a stable oxidation product, poses challenges for reduction through light energy alone, necessitating the use of catalysts. Thus, a crucial aspect of CO2 photocatalytic reduction technology lies in the development of effective photocatalysts. Based on the basic principle of PCRR (photocatalytic CO2 reduction reaction), the review provides a detailed introduction to the core issues in PCRR process, including the relationship between band gap and catalyst reduction performance, effective utilization of photogenerated carriers, product selectivity, and methods for product analysis. Then, the recent research progresses of various photocatalysts are reviewed in the form of research examples combined with the above basic principles. Finally, this review summarizes and provides insights into the effective techniques for enhancing the photocatalytic activity of CO2, while also offering future prospects in this field.
