a UV-DRS spectra of In2O3, Pd-In2O3 and Pd-def-In2O3. Insert shows the optical images of In2O3, Pd-In2O3 and Pd-def-In2O3. b In situ Pd3d XPS spectra of Pd0.3-def-In2O3 in dark and under extended light irradiation. Solid-state in situ EPR spectra of c In2O3, d Pd-In2O3 and e, f Pd-def-In2O3 in dark and under light irradiation for different reaction time.
