Description
To unlock the potential of electrochemical reduction of waste CO2 emissions (CO2RR) to facilitate decarbonisation efforts, we have developed a series of single-atom catalysts, incorporating inexpensive Ni. Our preliminary mechanistic investigations reveal that changing coordination environment can affect both catalytic activity and tolerance towards impurities in flue gas. In situ x-ray absorption spectroscopy (XAS) measurements is undertaken to (i) evaluate the structure and stability of these catalysts after CO2RR, (ii) investigate the interaction of impurities (NO2-, SCN) with the active sites- key for industrial scalability and (iii) examine the nature of the redox processes that take place centred on the SACs in situ. The in situ XAS experiment reveal clear differences between substrates can be seen. Our finding contributes both to understanding the processes of CO2 reduction and also impurity tolerance of the catalysts.
