CO2 capture-reduction (CCR) study of Fe, Co and Cu promoted K and/or Na-Al2O3 samples - APR 2025

CO2 capture-reduction (CCR) is a recently developed catalytic process that combines two critical functions of the CO2 utilization path in one process, namely CO2 capture and subsequent transformation (e.g. reduction by H2) into chemical fuels or intermediates such as CO. A bifunctional catalyst material is needed and the two functions are activated by means of an isothermal unsteady-state operation (i.e. gas switching). This work employs operando space- and time-resolved XAS and XRD to elucidate the nature and functions of metal and the promoters involved in the process.
