摘要
CO_2资源化不但可以解决温室效应引起的环境问题同时又可以解决日益严峻的能源枯竭问题,利用光催化转化技术是固定CO_2的理想途径之一,促进光催化固定二氧化碳技术的核心课题是研发高效新型可见光响应的光催化材料。然而,传统的半导体光催化剂在还原CO_2的反应中可见光利用率低且催化活性也比较低。金属有机骨架材料的不断发展为我们研发具有高催化活性的光催化剂带来了希望。本文重点阐述了不同光催化材料对还原CO_2的研究现状及存在的问题,并对其发展趋势作了展望。
The utilization of CO2 could not only solve the environmental problems caused by the greenhouse effect, but also relieve the resources shortage. Photocatalytic CO2 fixation has been becoming one of the most promising solutions to mitigate CO2 emissions. Therefore, the development of new visible-light-induced photocatalysts is considered as a key step for the efficient utilization of CO2 by photocatalytic reduction technology. Metal-organic frameworks （MOFs） represent a new class of hybrid porous materials, making them attractive in photocatalysis. This paper was focused on the research process for the reduction of CO2 over various photocatalysts in recent years. Meanwhile, the developing trends ofphotocatalytic reduction of CO2 are also prospected,
