a Faradaic efficiency (FE) of CO (solid) and H2 (square grid) production on Au NCs (red), RDs (yellow) and OCs (purple) in an electrocatalytic CO2 reduction system. The error bars denote the standard deviation obtained from three independent measurements. b Change in the absolute value of FE for CO and H2 [FElight - FEdark] on Au NPs when illuminated by a 525 nm LED. c Percentage change in partial current density for CO (solid line) and H2 (dotted line) [( jlight-jdark)/jdark × 100%] on Au NPs when illuminated. d Chopped-light chronoamperometry with 525 nm LED at −0.81 VRHE on Au NPs.

a–c Faradaic efficiencies (FE) for CO production at different applied potentials on (a) Au NCs, (b) RDs, and (c) OCs at room temperature (solid), 30 °C (dense slash) and 40 °C (sparse slash). d–f Hot electron (solid) and hole (dashed) generation rate for each of the (d) Au NCs, (e) RDs, and (f) OCs at different electric field wavelengths. Ne/h(E,ω) indicates the number of hot carriers being generated with energy E upon the light with ω. The Fermi energy is set to zero. g–i Absolute electric field profile in (g) Au NCs, (h) RDs, and (i) OCs at the corresponding LSPR frequencies, in reference to the external applied electric field. All simulated nanoparticles have approximately 200,000 atoms. Source data are provided as a Source Data file
