Recent progress in microporous membrane reactors for catalytic conversion CO2 into value-added chemicals

Catalytic conversion of CO 2 into high value-added chemicals offers an attractive route to address a range of climate issues caused by excessive CO 2 emission. However, the chemical inertness of CO 2 generally leads to unsatisfied CO 2 conversion and product selectivity. Catalytic membrane reactors (CMRs) have been considered promising to break the thermodynamic equilibrium of CO 2 catalytic reactions. This review firstly provides an overview of chemical reactions utilizing CO 2 and the classification of potential CO 2 -derived chemical products. Then, the fundamentals of catalytic CO 2 conversion and the analysis of opportunities and difficulties of such reactions are presented. The advances of microporous membrane-based CMRs are deeply discussed regarding the membrane materials, applications for common chemical synthesis and reactor designs. Finally, the current achievements and future outlook in microporous membrane reactors (MMRs) for CO 2 catalytic conversion are summarized.
