a) Scheme for electron transfer processes occurring in CdSe quantum dot‐sensitized photocathode in the presence of cocatalyst. b) Linear sweep voltammograms under 520 nm LED light (150 mW) illumination of (1) bare NiO film, (2) NiO‐S3‐cap‐CdSe, (3) NiO‐S3‐cap‐CdSe with Ni(DHLA)x, (4) NiO‐S3‐cap‐CdSe with [Co(bdt)2]−, and NiO‐S3‐cap‐CdSe without illumination at 0.1 m KCl solution (pH = 6). c) Controlled potential bulk photo‐electrolysis experiments for NiO‐S3‐cap‐CdSe/[Co(bdt)2] under light and dark conditions. d) Experimentally observed (red circles) and theoretically calculated (black dashed line) H2 production versus time for NiO‐S3‐cap‐CdSe with [Co(bdt)2]− (1.85 × 10−4 m) at an applied potential of ‐0.28 V versus RHE.
