摘　　要：利用光催化技术将CO_(2)转化为CO、CH_(4)及C_(2+)等高附加值化学品,是同时解决温室效应和能源危机的有效策略。在催化材料中引入空位缺陷,构建缺陷能级,从而改变材料电子结构和带隙,可拓宽其光谱响应范围,增加反应活性位点,降低反应活化能,提高光催化性能。本综述从三个方面阐述空位缺陷材料光催化还原CO_(2)研究进展,包括空位缺陷材料的类型和制备方法;光催化还原CO_(2)反应基本原理与反应评价以及不同空位缺陷光催化还原CO_(2)体系,对后续研究空位缺陷在光催化还原CO_(2)中的作用和机理具有重要参考价值。The utilization of photocatalysis technology for the conversion of CO_(2) into high value-added chemicals such as CO,CH_(4) and C_(2+) represents an effective strategy to simultaneously address the greenhouse effect and energy crisis.Introducing vacancies into the catalytic materials can change their electronic structures and band gaps,generate defect energy levels,broaden the spectral response range of the materials,increase the reactive sites,reduce the activation energy of the reaction,and enhance the conversion efficiency of the photocatalytic reaction.The research progress on photocatalytic reduction of CO_(2) by vacancy-defect materials was described from three aspects,including the types and preparation methods of vacancy-defect materials,the basic principles of photocatalytic reduction of CO_(2) reaction and the evaluation of the reaction,as well as the different vacancy-defect photocatalytic reduction of CO_(2) systems.It had important reference value for the subsequent research on the role and mechanism of vacancy defects in photocatalytic CO_(2) reduction.
