摘要:

随着能源短缺和环境问题日益突出, 寻找清洁和可再生能源来替代化石燃料是本世纪科学家面临的最紧迫的任务之一. 为了实现我国“双碳”战略目标, 利用太阳能将二氧化碳(CO2)转化为清洁燃料和化学品是实现社会可持续发展的途径之一. 催化剂是CO2光还原技术的核心组成部分, 其可以吸附气态CO2分子, 在可见光照射下将CO2还原为一氧化碳(CO)、 甲酸(HCOOH)、 甲醇(CH3OH)或甲烷(CH4)等能源小分子. 目前, 新型CO2还原光催化体系的开发取得了很好的进展. 本文综合评述了近年来均相及非均相丰产金属卟啉类催化剂在光催化CO2还原中的研究进展, 并对在金属卟啉均相催化剂作用下, CO2光还原为CO或CH4的反应机理分别进行了介绍, 还讨论了金属卟啉基多孔有机聚合物与卟啉有机金属框架在光催化CO2方面的重要应用. 最后, 对可见光驱动卟啉类金属配合物催化的CO2还原的发展前景进行了展望.

Abstract:

With the increasing energy shortage and environmental problems, the search for clean and renewable energy sources to replace fossil fuels is one of the most urgent tasks facing scientists in this century. In order to achieve our "carbon neutrality" strategic goal, the conversion of carbon dioxide(CO2) into clean fuels and chemicals using solar energy is one of the ways to achieve the sustainable development of our society. The catalyst is the core component of CO2 photoreduction technology, which can adsorb gaseous CO2 molecules and reduce them to small energy molecules such as carbon monoxide(CO), formic acid(HCOOH), methanol(CH3OH) and methane(CH4) under visible light irradiation. Currently, promising progress has been made in the development of novel CO2 reduction photocatalytic systems. This review summarizes the recent progress of homogeneous and heterogeneous earth-abundant metalloporphyrin-based catalysts for photocatalytic CO2 reduction, and introduces the reaction mechanism of CO2 photoreduction to CO or CH4 by homogeneous metalporphyrin catalysts, respectively, and also discusses the important applications of metalloporphyrin-based porous organic polymers with porphyrin organometallic frameworks for photocatalytic CO2 reduction. Finally, the prospect of visible-light-driven metalloporphyrin complex-catalyzed CO2 reduction is presented.
