WAXS study of Cu-Ag catalysts for CO electroreduction to C2+ - probing the formation of active phases upon reduction


Raising environmental concerns constitutes a driving force towards the development of sustainable technologies to produce chemicals. The electroreduction of CO (CORR) to fuels is one of these technologies. C1 (methane, methanol) and C2+ products (ethylene, ethanol, propanol etc.) can be produced via the electroreduction of CO, derived from CO2 or CO-rich waste streams [1]. CO is a key intermediate in the C2+ products formation during widely studied CO2RR. Using CO as a feed gas is a novel approach and improves the selectivity towards C2+ molecules. Cu is the only element active for C-C coupling but exhibits low selectivity [1,2]. The addition of Ag is reported to promote the presence of residual Cu2O in the catalysts important for C-C coupling [3]. We prepared and studied several Cu-Ag catalysts with varying compositions with improved catalytic performance towards C2+ products. Our goal is to investigate the impact of Ag on the performance of these Cu-based catalysts by WAXS.
