Fig. 4: Catalytic performance of Au-catalysts for CO2R.

a Current density (jCO) versus applied potential (E vs. RHE) for Au nanocatalysts: nanotriangles (AuNTs), nanodisks (AuNDs), nanoparticles (AuNPs), and commercial powders (AuCPs). b Faradaic efficiency for CO (FECO) at different applied potentials. c Half-cell cathodic energy efficiency (CEE) as a function of applied potential. d Stability test for AuNTs at −1.0 V vs. RHE over 100 h. The total current density (jtotal) remains stable, and FECO is consistently high, indicating durable long-term performance. e Cyclic voltammograms for AuNTs, AuNDs, AuNPs, and AuCPs in 50 mM H2SO4. The error bars and bands correspond to the standard deviation of three independent measurements.
