The direct hydrogenation of greenhouse gas CO2 to higher alcohols (C2+OH) provides a new route for the production high-value chemicals. Due difficulty C-C coupling, formation is more difficult compared that other compounds. In this review, we summarize recent advances in development multifunctional catalysts, including noble metal Co-based Cu-based Fe-based and tandem catalysts alcohols. Possible reaction mechanisms are discussed based on structure–activity relationship catalysts. reaction-coupling strategy holds great potential regulate network. effects conditions also analyzed. Finally, discuss challenges opportunities further

Hydrogenation of CO2 represents a promising pathway for converting it into valuable hydrocarbons and clean fuels like dimethyl ether (DME). Despite significant research, several challenges persist, including limited understanding reaction mechanisms, thermodynamics, the necessity catalyst design to enhance DME selectivity, issues related deactivation. The paper provides comprehensive overview recent studies from 2012 2023, covering various aspects hydrogenation methanol DME. This review primarily focuses on advancing development efficient, selective, stable innovative catalysts this purpose. Recent investigations that have extensively explored heterogeneous were summarized. A notable focus is Cu-based modified with promoters such as Zn, Zr, Fe, etc. Additionally, context delves thermodynamic considerations, impact variables, reactor configurations, technological advancements, 3D-printed catalysts. Furthermore, examines influence different parameters offers insights direct proposes paths future investigation, aiming address current advance field.
