摘　　要：大气中二氧化碳(CO_(2))浓度的增加对人类赖以生存的地球环境产生了严重的负面影响,因此,减少和降低大气中CO_(2)的浓度迫在眉睫。其中,借助太阳能、风能等可再生能源获得的绿色低成本氢气,将CO_(2)加氢转化为高附加值的甲醇,将有助于减少CO_(2)排放,助推碳中和目标的实现。铜基催化剂因其具有良好的活性和甲醇选择性,一直是CO_(2)加氢制甲醇催化领域的研究重点。本工作综述了近年来CO_(2)加氢制甲醇铜基催化剂的研究进展,首先对CO_(2)加氢制甲醇反应进行了热力学与反应机理分析;其次,探讨了助剂、载体以及制备方法对铜基催化剂物化性质及催化性能的影响;随后,讨论了CO_(2)加氢制甲醇的工业化进展;最后,对当前铜基催化剂催化CO_(2)加氢制甲醇的挑战以及未来研究趋势进行了总结与展望。The increasing concentration of carbon dioxide(CO_(2))in the atmosphere poses a significant environmental challenge,with extensive negative effects on the Earth's environment and human survival.To tackle this issue,scientists are actively exploring various innovative technologies.One promising approach involves using renewable energy sources,such as solar and wind,to produce low-cost green hydrogen,which can then hydrogenate CO_(2)into high-value-added methanol.This strategy not only helps reduce CO_(2)emissions but also supports carbon neutrality and sustainable development goals.The core of the CO_(2)hydrogenation to methanol technology lies in leveraging renewable energy to generate low-cost green hydrogen,which reacts with CO_(2)to produce methanol.This process is considered to be an efficient method of carbon recycling and utilization.Copper-based catalysts are particularly noteworthy for their excellent activity and selectivity in producing methanol.The research and application of these catalysts highlight their crucial role in addressing climate change and energy security challenges.Advancements in this technology provide essential scientific support for reducing greenhouse gas emissions,promoting carbon neutrality,and achieving sustainable development.They also lay a solid foundation for a clean,green energy future.Recent studies have shown that a deeper understanding of the thermodynamic and kinetic mechanisms of these reactions enables scientists to optimize catalyst design,enhancing their stability,activity and selectivity.Firstly,this work reviews the recent progress in the research of copper-based catalysts for CO_(2)hydrogenation to methanol.It analyzes the thermodynamics and reaction mechanism of the CO_(2)hydrogenation to methanol reaction,detailing the basic principles and revealing the key steps in the reaction pathway.These theoretical foundations provide important guidance for further experiments and engineering optimization.Secondly,the study focuses on the physicochemical properties of coppe
