Fig. 12. (a) LSV curves of Au47Cd2(TBBT)31, Au44(TBBT)28 and the ca.1.5 nm Au NPs in an Ar-saturated (dotted line) and a CO2-saturated (full line) 0.5 m KHCO3 solution; inset: enlarged LSV curves from @0.1 V to @0.6 V. (b) CO faradaic efficiency for the catalysts examined with different applied potentials. (c) The corresponding CO partial current density. (d) The stability test conducted at @0.57 V for Au47Cd2(TBBT)31 and Au44 and at @0.67 V for the Au NPs. Reproduced with permission.106 Copyright 2019 Wiley-VCH.
