A Schematic and energy level diagram illuminating hot-electron injection from Au NPs to POMs. B The Au 4 f XPS spectra of Au@POMs with and without light irradiation. C The W 4 f XPS spectra of Au@POMs with and without light irradiation. D Dark-field scattering spectroscopy of single Au and Au@POMs NP (the intensities are normalized). The inset is dark-field image of a single particle of Au@POMs deposited on an ITO slide. E Chronopotentiometry of the Voc from Au and Au@POMs under light irradiation. F Nyquist plots of Au@POMs NPs with light on and off collected at open-circuit potential. Source data are provided as a Source Data file.
