Technologies and approaches developed for converting CO2 to useful products offer opportunities to mitigate CO2 emissions while generating revenues to offset the costs associated with carbon management. Hydrogenation of CO2 to methanol is a viable option because methanol can be directly utilized as a fuel or easily converted to various industrial chemicals. Currently, methanol is produced from syngas on Cu/ZnO/Al2O3 catalysts. However, the low activity and stability of existing formulations constitute a major hurdle towards using them in realistic CO2-rich conditions. Current literature shows that there is no consensus on the identity of active sites, role of ZnO, and effects of promoters. Therefore, a thorough understanding of the catalytic phenomena involved in producing methanol from CO2 will bring us much closer to the rational design of efficient catalysts.
