Zeolite membrane reactors for efficient catalytic conversion of CO₂ into high-value chemicals

Converting CO₂ into high-value chemicals is vital for achieving carbon capture and utilization. Although many advanced catalysts have been developed to activate the thermodynamically stable CO₂ molecules, overcoming equilibrium limitations remains essential for improving conversion efficiency. Zeolite membrane reactors (ZMRs) have been explored to overcome thermodynamic constraints and further improve conversion efficiency. This review provides insights into catalyst evolution and highlights the pivotal role of zeolite membranes in enhancing CO₂ conversion to high-value chemicals such as methanol, dimethyl ether and dimethyl carbonate within ZMRs. An overview of zeolite membrane selection, preparation and catalyst-membrane coupling strategies is presented, along with recent advances in process modeling to elucidate reaction-separation interactions. The stability of ZMR systems under practical conditions is also discussed. Finally, future perspectives, identifying key challenges and potential research directions, are presented. This review aims to inspire further innovations in efficient CO₂ conversion to high-value chemicals using ZMRs.
