Fig. 3

a Schematic diagram of the process of storing electrons and hydrogen atoms. The structural models were created using VESTA47. b EPR spectra of Cu/WO3 after different times of light irradiation. c 1H NMR spectra of Cu/WO3 and Cu/HxWO3. d FTIR spectra of Cu/WO3, Cu/HxWO3 and Cu/DxWO3. e Wavelength-dependent AQE of H2O to electron−hydrogen pairs. f Normalized W L3-edge XANES spectra of Cu/WO3, Cu/HxWO3 and W foil. g W L3-edge EXAFS spectra of Cu/WO3 and Cu/HxWO3.
