Recent Progress in the Integration of CO Capture and Utilization.

CO emission is deemed to be mainly responsible for global warming. To reduce CO emissions into the atmosphere and to use it as a carbon source, CO capture and its conversion into valuable chemicals is greatly desirable. To reduce the transportation cost, the integration of the capture and utilization processes is a feasible option. Here, the recent progress in the integration of CO capture and conversion is reviewed. The absorption, adsorption, and electrochemical separation capture processes integrated with several utilization processes, such as CO hydrogenation, reverse water-gas shift reaction, or dry methane reforming, is discussed in detail. The integration of capture and conversion over dual functional materials is also discussed. This review is aimed to encourage more efforts devoted to the integration of CO capture and utilization, and thus contribute to carbon neutrality around the world.
