a LSV curves, (b) Tafel slopes, and (c) chronoamperometric I-t curves at −0.8 V (vs Ag/AgCl) for Au-[Fe(bpy)3]2+ and controls in dark or with irradiation. d Photoelectrochemical hydrogen production of Au-[Fe(bpy)3]2+ under Xe light irradiation at −0.8 V. e Light-modulated photocurrent measured with an applied bias of −0.2 V with or without illumination at 100 mW/cm2. f Wavelength dependence of Au-[Fe(bpy)3]2+ catalytic Jphoto compared to its absorbance. g Plot of Au-[Fe(bpy)3]2+ Jphoto as a function of incident light power. h, i Raman nano-thermometry spectra of Au-[Fe(bpy)3]2+ at different temperatures (h) or after irradiation for 20 seconds (100 mW/cm2) (i). Error bars in all figures represent standard deviations of three independent measurements.
