摘　　要：工业发展带来了经济效益的同时,伴随着化石燃料的日益枯竭和CO_(2)的大量排放,加剧了温室效应,出现了全球变暖的问题。我国在倡导节能减排的同时,大力发展CO_(2)固定技术,将大气中丰富的CO_(2)转化为可以供人们利用的化工原料、燃料甚至更高附加值产品,不仅能够保护环境,同时还可提高经济效益。当前全球可再生能源规模的不断扩大缓解了传统能源消耗的压力,同时可再生能源可以为固定CO_(2)提供可持续的、清洁的驱动能量,并且随着分子生物学的发展,生物法固碳技术越发成熟,同时较其他固定CO_(2)方法而言,生物法固碳具有条件温和、选择性高、产品多样等优势,因此利用可再生能源耦合生物催化进行CO_(2)的固定逐渐成为了这一领域的研究重点。本文总结了近年来生物催化与电化学、光化学反应耦合固定CO_(2)的研究,包括光、电催化与酶催化偶联以及光、电催化与全细胞催化偶联对CO_(2)的利用,简述了其耦合催化原理与研究进展,并总结了目前研究需要突破的关键技术及提高CO_(2)催化转化效率的方法。Along with the depletion of fossil fuels,industrial development has brought economic benefits,but also leads to large amounts of CO_(2)emissions,which has aggravated the greenhouse effect and caused the problem of global warming.Upon the advocacy of energy conservation and pollution reduction,CO_(2)fixation technologies are vigorously developed in China to transform the abundant CO_(2)into chemical raw materials,fuels and even higher value-added products.It can not only protect the environment but also improve economic benefits.At present,the continuous expansion of the global renewable energy scale has relieved the pressure of traditional energy consumption,while renewable energy can provide a sustainable and clean driving force for CO_(2)fixation.Meanwhile,with the development of molecular biology,the biofixation technology of CO_(2)has become more and more mature.And compared with other fixation technology,bio-fixation of CO_(2)has various advantages including mild conditions,high selectivity and the diversity of products,which has gradually become the focus in this field.Herein the recent research on the coupling of biocatalysis with electrochemical and photochemical reactions for CO_(2)fixation was summarized including the coupling of photocatalysis or photoelectrocatalysis with enzyme catalysis,and the combination of photocatalysis or electrocatalysis with the whole-cell catalyst technology.The principle and research progress of these strategies were introduced,while the current issues in the field as well as the essential technologies to break through the conversion efficiency of CO_(2)were also prospected.
