Fig 4 Photoelectrochemical CO2 reduction with plasmonic Au/p-GaN photocathodes. (a) Time-course of gas evolution from plasmonic Au/p-GaN photocathode during controlled potential electrolysis under dark conditions. (b) Time-course of gas evolution from plasmonic Au/p-GaN photocathode during controlled potential electrolysis under plasmon excitation (λ > 495 nm). All electrolysis experiments were performed at ?1.8 VRHE in CO2-saturated 50 mmol?L?1 K2CO3 electrolyte without sacrificial reagents. Adapted from ACS Publications publisher 34.
