随着全球能源消耗的不断增长和环境污染问题的日益严重,寻找清洁、高效的CO_(2)利用路径成为研究热点。甲醇由于用途广泛,既是重要的化工原料,也是一种新型清洁能源。CO_(2)催化加氢制甲醇过程不仅实现CO_(2)减排,还是碳资源循环利用的有效途径之一,对解决能源紧缺和环境问题具有重要意义。高活性、高选择性和高稳定性的CO_(2)加氢制甲醇催化剂的开发一直是该过程的核心技术。本文综述了CO_(2)加氢制甲醇的研究进展,主要介绍了反应机理和催化剂,并以Cu基催化剂为重点总结了活性位、载体和助剂对催化性能的影响,最后对CO_(2)加氢制甲醇的应用前景进行了展望。

With the continuous growth of global energy consumption and the increasingly serious environmental pollution problem,finding a clean and efficient CO_(2)utilization path has become a research hotspot.Because of its wide use,methanol is not only an important chemical raw material,but also a new type of clean energy.The process of CO_(2)catalytic hydrogenation to methanol not only achieves CO_(2)emission reduction,but also is one of the effective ways to recycle carbon resources,which is of great significance to solve energy shortage and environmental problems.The development of catalysts with high activity,selectivity and stability for hydrogenation of CO_(2)to methanol has been the core technology of this process.This paper reviews the research progress in carbon dioxide hydrogenation to methanol,mainly introduces the reaction mechanism and catalyst,and focuses on the influence of the active site,support and additives on the catalytic performance of Cu-based catalyst.Finally,the application prospect of CO_(2)hydrogenation to methanol is prospected.
