Integrated CO2 capture and utilization (ICCU) can achieve the conversion of captured into value-added products in a single reactor, enabling it to be one fundamental approaches eliminating emissions future. The rational design dual-functional materials (DFMs) combining adsorption catalytic sites is crucial realizing an efficient ICCU process. This Perspective promotes understanding through integrated methanation, reverse water gas shift, dry reforming methane, other technologies, focusing on selection matching between DFMs for enhanced performance. Interactions are pivotal mechanism studies directing catalyst design. proximity effect induced adsorbent–catalyst interaction comprehensively evaluated provide perspective principle DFMs. will theoretical foundations selecting DFMs, promoting comprehensive enhancement performance, thus facilitating carbon reduction goals.
