CO2 capture and utilisation (CCU) is a sustainable process that can partially close the carbon cycle. It is attractive to store the excess and uncertain supply of energy from renewable sources to stable chemical energy. Increasing studies have been carried out on integrated CO2 capture and utilisation (ICCU) to reduce the cost of the overall process by eliminating the transportation and storage of CO2. ICCU could achieve in-situ CO2 adsorption, separation and conversion using dual-function catalysts (DFMs), consisting of CO2 adsorbents and catalysts. ICCU avoid temperature swing sorbent regeneration, which is considered an energy-intensive process. Integrating CO2 capture and utilisation via reverse water-gas shift reaction (ICCU-RWGS) is particularly attractive due to the important industrial value of syngas. Furthermore, the in-situ CO2 utilisation can outperform conventional RWGS in relation to CO2 conversion and CO selectivity. Herein, we achieved very promising ICCU-RWGS performance by CaO-alone and functionalising CaO using active transition metals (e.g. Ni and Fe). Excellent CO2 adsorption and extremely efficient CO2 conversion can be achieved with simple materials, outperforming traditional separated CO2 capture and catalytic conversion processes.

Dr Chunfei Wu

at QUB

Dr Chunfei Wu (CW) is a Reader at the School of Chemistry and Chemical Engineering and the Chemical Engineering Programme Lead at QUB. He has worked in the areas of converting renewable and waste resources to energy, fuel, and chemicals through catalytic thermochemical routes for more than 15 years. He is the PI of a EU RISE international exchange programme in relation to biomass gasification and carbon capture and utilisation (Ref; EU823745, €864,400) (2019-2022), coordinating 15 research groups. Dr Wu has also been involved in several EPSRC, Innovate UK, Royal Society and other EU projects. For example, he is the Co-I in EP/R000670/1 using microwave for bio-oil upgrading; Co-I in Innovate UK (Ref: 29478) for advanced battery thermal control and thermal using thermal phase change materials; Host academic for a Royal Society K.C. Wong International Fellowship (Ref: NIF\R1\191817). He has published >200 peer-reviewed journal papers with >9100 citations (H index of 57, Google Scholar). He is the Managing Editor of Biomass and Bioenergy, and he is a Charted Scientist and a Member of Royal Society of Chemistry. He is also the Founding Editor-in-Chief of Carbon Capture Science & Technology, a Gold Open Access journal published by Elsevier.
