Abstract

Carbon capture and utilization (CCU) represent a promising strategy to reduce CO2 emissions and promote a sustainable economy. We report an integrated CCU (ICCU) process by integrating CO2 capture with reverse water gas shift reaction by applying simple and low-cost CaO as both sorbent and catalyst....
