1. Introduction
Methanol is mainly produced from synthesis gas, which is usually obtained from methane or coal.1 Although currently there is surplus global methanol production capacity2, with the continuous development of methanol applications, methanol—which is the cornerstone product of C1 chemistry—has promising market prospects3. Recently, the production of “bioethanol” has commenced at a new plant for processing biomass synthesis gas4. Methanol can now be considered as a sustainable platform compound with very promising chemical applications.
