Human CO emissions are an important driving factor in global warming, which is a threat to the Earth's climate system and ecosystems, with consequences such as increased average global temperature, frequent extreme heat waves, and ecosystem degradation. Nowadays, all CO storage technologies still face a number of challenges, such as cost, capacity of treatment, and energy consumption. Among all Carbon Capture, Utilization, and Storage methods, hydrogenation of CO into methanol (CHOH) has become one of the vital ways to deal with carbon dioxide, and at the same time, high-value chemicals and fuels were prepared. This article systematically reviews the catalytic systems adopted in the CO hydrogenation to methanol process, mainly focusing on different catalyst types and giving an in-depth explanation of their reaction mechanisms. Meanwhile, a flow diagram was adopted to depict the integral process of this reaction under industrial conditions, involving key unit operations. The study shows that efficient catalysts and low-cost green hydrogen are the keys to the successful industrial application of this technology, and its extensive application will provide a good prospect for a green future.
