This review explains the various methods of conversion of Carbon dioxide (CO) to methanol by using homogenous, heterogeneous catalysts through hydrogenation, photochemical, electrochemical, and photo-electrochemical techniques. Since, CO is the major contributor to global warming, its utilization for the production of fuels and chemicals is one of the best ways to save our environment in a sustainable manner. However, as the CO is very stable and less reactive, a proper method and catalyst development is most important to break the CO bond to produce valuable chemicals like methanol. Litertaure says the catalyt types, ratio and it surface structure along with the temperature and pressure are the most controlling parameters to optimize the process for the production of methanol from CO. This article explains about the various controlling parameters of synthesis of Methanol from CO along with the advantages and drawbacks of each process. The mechanism of each synthesis process in presence of metal supported catalyst is described. Basically the activity of Cu supported catalyst and its stability based on the activity for the methanol synthesis from CO through various methods is critically described.
这篇综述解释了通过均相、多相催化剂，利用加氢、光化学、电化学和光电化学技术将二氧化碳（CO）转化为甲醇的各种方法。由于 CO 是全球变暖的主要贡献者，因此将其用于生产燃料和化学品是可持续方式保护环境的最佳方法之一。然而，由于 CO 非常稳定且反应性较低，因此开发适当的方法和催化剂对于打破 CO 键以生产有价值的化学品（如甲醇）非常重要。文献表明，催化剂类型、比例及其表面结构以及温度和压力是优化 CO 生产甲醇过程的最重要控制参数。本文解释了从 CO 合成甲醇的各种控制参数，以及每个过程的优缺点。描述了在金属负载催化剂存在下的每个合成过程的机理。基本上，根据通过各种方法从 CO 合成甲醇的活性，对 Cu 负载催化剂的活性及其稳定性进行了批判性描述。
