(513z) Smart Catalyst Design for Chemical CO2 Recycling: Reforming and Hydrogenation As Case Study

Chemical CO₂ recycling in gas phase constitutes one of the straightforward approaches for effective CO₂ conversion to added value products like syngas or synthetic methane. In this scenario, some traditional processes such as the dry and bi reforming of methane, the CO₂ methanation and the reverse water gas shift have gained a renewed interest from the CO₂ utilisation perspective. Indeed, these reactions represent flexible routes to upgrade CO₂ and their application at industrial scale could substantially reduce CO₂ emissions. The bottle neck for the implementation of these processes at industrial scale is the development of highly active and robust heterogeneous catalysts able to overcome the CO₂ activation and deliver sufficient amounts of the upgrading products (i.e. syngas or synthetic natural gas) at the desired operation conditions. In this work, we will showcase different strategies developed at Surrey to design highly effective catalysts for the processes mentioned above using multicomponent materials. Particular emphasis is given to the catalysts’ stability for long-term runs and its potential application to upgrade industrial flue gas mixtures.
