摘　　要：近年来,全球能源危机和环境问题已经成为重大挑战,而过度使用化石燃料是导致这些问题的主要原因之一。为了解决能源短缺和过量CO_(2)排放问题,太阳能驱动下的光催化CO_(2)还原被认为是有效的策略之一。为了提高二氧化碳光催化还原的效率,文章通过回顾气固相光反应器的发展过程,对光催化CO_(2)还原的基本机制和光反应器设计进行了分析,并总结了其优势和不可避免的局限性。通过剖析不同类型的光反应器结构及其操作动态,可以对数据收集和分析提供指导,以便探索其增长轨迹和未来可能性,为实现碳中和目标提供启示。光催化CO_(2)还原技术作为一种可持续且具有潜力的解决方案,将在实现这一目标的过程中发挥关键作用。In recent years,the global energy crisis and environmental issues have become significant challenges,and excessive use of fossil fuels is one of the main causes of these problems.In order to address the shortage of energy and excessive CO_(2)emissions,photocatalytic CO_(2)reduction driven by solar energy is considered one of the most effective strategies.Currently,research on improving the efficiency of CO_(2)photocatalytic reduction mainly focuses on the following aspects:modifying the properties of photocatalysts to prevent electron-hole recombination,optimizing reaction conditions to achieve maximum yield,and constructing efficient photoreactors to enhance the adsorption process.In this review,we analyze the development process of gas-solid phase photoreactors,discuss the fundamental mechanism of photocatalytic CO_(2)reduction and photoreactor design,and summarize their advantages and inevitable limitations.By analyzing the structures and operating dynamics of different types of photoreactors,guidance can be provided for data collection and analysis,in order to explore their growth trajectory and future possibilities,and provide insights for achieving carbon neutrality research goals.Photocatalytic CO_(2)reduction technology,as a sustainable and promising solution,will play a key role in the process of achieving this goal.
