Ethylene glycol (EG), a useful chemical raw material, has been widely applied in many aspects of modern society. The conventional preparation of ethylene glycol mainly uses the petroleum route at high temperatures and pressure. More and more approaches have been developed to synthesize EG from CO and its derivatives under mild conditions. In this review, the ambient synthesis of EG from thermocatalysis, photocatalysis, and electrocatalysis is highlighted. The coal-to-ethylene glycol technology, one of the typical thermal catalysis routes for EG preparation, is relatively mature. However, it still faces some problems to be solved in industrialization. The recent progress in the development of coal-to-ethylene glycol technology is introduced. The main focus is on how to realize the preparation of EG under mild conditions. The strategies include doping promoters, modification of supports, design of catalysts with special structures, Furthermore, the emerging technological progress of photocatalytic and electrocatalytic ethylene glycol synthesis under ambient conditions is introduced. Compared with the thermal catalytic reaction, the reaction conditions are milder. However, there are still many problems in large-scale production. Finally, we propose future development issues and related prospects for the ambient synthesis of EG using different catalytic routes.
乙二醇（EG）作为一种有用的化学原料，已在现代社会的许多方面得到广泛应用。传统的乙二醇制备主要采用高温高压的石油路线。越来越多的方法已被开发出来，用于在温和条件下由一氧化碳及其衍生物合成乙二醇。在这篇综述中，重点介绍了通过热催化、光催化和电催化在环境条件下合成乙二醇的方法。煤制乙二醇技术作为制备乙二醇的典型热催化路线之一，相对成熟。然而，它在工业化过程中仍面临一些有待解决的问题。介绍了煤制乙二醇技术发展的最新进展。主要关注如何在温和条件下实现乙二醇的制备。策略包括掺杂促进剂、修饰载体、设计具有特殊结构的催化剂。此外，还介绍了在环境条件下光催化和电催化合成乙二醇的新兴技术进展。与热催化反应相比，反应条件更温和。然而，大规模生产中仍存在许多问题。最后，我们提出了使用不同催化路线在环境条件下合成乙二醇的未来发展问题及相关前景。
