Abstract: Mitigating CO2 to minimize the steady rise in global temperature is a pressing topic and the scientific community is putting every effort to reduce CO2 emissions from major point sources such as steel or cement industries. This research topic investigates on CO2 hydrogenation to valuable products like CO, CH4 etc. over single-atom catalysts (SACs) and further compare the activity and selectivity over supported cluster and nano-particle catalysts. To understand the evolution of the catalytically active center, in-situ/operando diffuse reflectance Infra-red (DRIFTS) spectroscopy and X-ray absorption spectroscopy (XAS) will be used. In addition, kinetics and reaction mechanism for CO2 hydrogenation pathway will be investigated in details with findings of plausible formate, carbonate or any other intermediate that might involve during the course of the reaction.
