摘要
工业革命以来,化石燃料的大规模消耗导致大气中二氧化碳(CO_(2))浓度持续攀升,引发的全球变暖与气候变化已成为全球性重大环境挑战,发展碳中和技术势在必行。光催化CO_(2)还原反应(CO_(2)RR)以太阳能为驱动,可在温和条件下将CO_(2)转化为高附加值化学品或燃料,兼具温室气体减排与可持续能源生产的双重优势,是实现“双碳”目标的关键技术之一。金属有机框架(MOFs)作为一类结构可精准设计的晶态多孔材料,具有超高比表面积、可调的孔隙结构与丰富的活性位点,为协同解决光催化CO_(2)RR中CO_(2)吸附活化弱、光捕获有限及光生载流子复合快等关键瓶颈提供了理想的材料平台。系统阐述了光催化CO_(2)RR的核心机理,重点梳理了MOFs基光催化剂的设计与改性策略及其性能优化机制,并针对现存挑战对该领域的未来发展方向进行了展望。
Since the Industrial Revolution,the large-scale consumption of fossil fuels has led to a continuous rise in atmospheric carbon dioxide(CO_(2))concentrations.The resulting global warming and climate change have become major global environmental challenges,making the development of carbon-neutral technologies imperative.Photocatalytic CO_(2) reduction reactions(CO_(2)RR),powered by solar energy,convert CO_(2) into high-value-added chemicals or fuels under mild conditions.Combining greenhouse gas reduction with sustainable energy production,a key technology for achieving the dual carbon goals was represented.Metal-organic frameworks(MOFs),as a class of structurally precisely designed crystalline porous materials,possess ultra-high specific surface areas,tunable pore structures,and abundant active sites.An ideal material platform for synergistically addressing key bottlenecks in photocatalytic CO_(2)RR was provided,such as weak CO_(2) adsorption and activation,limited light harvesting,and rapid recombination of photo-generated charge carriers.This paper systematically elucidated the core mechanisms of photocatalytic CO_(2)RR,focusing on the design and modification strategies for MOF-based photocatalysts alongside their performance optimisation mechanisms.It further outlines future development directions for this field in response to existing challenges.
