Dimethyl carbonate is a generally used chemical substance which is environmentally sustainable in nature and used in a range of industrial applications as intermediate. Although various methods, including methanol phosgenation, transesterification and oxidative carbonylation of methanol, have been developed for large-scale industrial production of DMC, they are expensive, unsafe and use noxious raw materials. Green production of DMC from CO and methanol is the most appropriate and eco-friendly method. Numerous catalysts were studied and tested in this regard. The issues of low yield and difficulty in tests have not been resolved fundamentally, which is caused by the inherent problems of the synthetic pathway and limitations imposed by thermodynamics. Electron-assisted activation of CO and membrane reactors which can separate products in real-time giving a maximum yield of DMC are also being used in the quest to find more effective production method. In this review paper, we deeply addressed green production methods of DMC using Zr/Ce/Cu-based nanocomposites as catalysts. Moreover, the relationship between the structure and activity of catalysts, catalytic mechanisms, molecular activation and active sites identification of catalysts are also discussed.
碳酸二甲酯是一种普遍使用的化学物质，在自然界中具有可持续性，并且在各种工业应用中用作中间体。虽然已经开发出甲醇光气化、酯交换和甲醇氧化羰基化等各种方法来大规模工业生产 DMC，但这些方法昂贵、不安全且使用有毒原料。从 CO 和甲醇绿色生产 DMC 是最合适和环保的方法。在这方面已经研究和测试了许多催化剂。但是，由于合成途径的固有问题和热力学的限制，产率低和测试困难的问题尚未得到根本解决。电子辅助 CO 活化和可以实时分离产物的膜反应器也被用于寻找更有效的生产方法。在这篇综述论文中，我们深入探讨了使用 Zr/Ce/Cu 基纳米复合材料作为催化剂的 DMC 绿色生产方法。此外，还讨论了催化剂的结构和活性、催化机制、分子活化和活性位点鉴定之间的关系。
