a, b HAADF-STEM image (a) and STEM-EDS mapping (b) of Rh/In2O3. c High-resolution In 3d XPS spectra of In2O3 and Rh/In2O3. d High-resolution Rh 3d XPS spectrum of Rh/In2O3. e, f XANES spectra at the In K-edge (e) and Rh K-edge (f) of Rh/In2O3. g EXAFS spectra at the Rh K-edge of Rh/In2O3. The corresponding spectra of In2O3, Rh2O3, and metal foils are used as references in e-g. Source data are provided as a Source Data file.
