Abstract:

Carbon capture and utilization(CCU) technologies play key roles in controlling carbon emission and net zero, but the deployment of which are restricted by the complex intermediate steps and high energy and capital investment. Integrated carbon dioxide capture and utilization(ICCU) can synergistically achieve CO_2 upgrading and adsorbent regeneration through in-situ catalytic conversion,avoiding the energy-consuming intermediate steps such as temperature-pressure swing and CO_2 compression,storage and transportation in conventional CCU technologies,exhibiting a highly competitive industrial application prospect. This review summarizes the updated research progress in the field of ICCU. Classified by the reaction integrated with CO_2 capture, the design principle of“capture-catalysis” dual-functional materials(DFMs) are concluded,the structure-activity relationship between DFMs and carbon capture and catalytic conversion performance is discussed,and the reaction mechanism of in-situ catalytic conversion is comprehensively reviewed. Combined with non-thermal catalytic conversion technology, this paper reviews the frontier research progress and looks forward to its development prospects and directions in the field of ICCU. Based on the ICCU design coupled with other high-carbon emission processes, we expand the relevant application scenarios and provides ideas for related process innovation. This review summarizes the current status, prospects, and opportunities of ICCU systems and DFMs systems, and provides a comprehensive evaluation from materials to processes,providing an important reference for future research and industrialization of ICCU.
