Dealloying-derived nanoporous Sn-doped copper with prior selectivity toward formate for CO2 electrochemical reduction

We report nanoporous Cu–Sn catalysts fabricated by chemically dealloying rapid solidified Al–Cu–Sn alloys for the CO2RR. The np-Cu11Sn1 catalyst exhibits a three-dimensional interconnected ligament-channel network structure, which can efficiently convert CO2 to formate with a Faradaic efficiency (FE...

Zusammenfassung:We report nanoporous Cu–Sn catalysts fabricated by chemically dealloying rapid solidified Al–Cu–Sn alloys for the CO2RR. The np-Cu11Sn1 catalyst exhibits a three-dimensional interconnected ligament-channel network structure, which can efficiently convert CO2 to formate with a Faradaic efficiency (FE) of 72.1% at −1.0 V (vs. RHE).
