a In situ EPR spectra at a S/C molar ratio of 1/1 under ambient and 290 °C conditions. b Sabatier-type correlations between Cd–O coordination number, Cd oxidation state, and H2 production rate. c Atomic-resolution HAADF-STEM with Ti L-edge EELS spectra across anatase/rutile interface. d Electrochemical CV curves in 0.1 M H2SO4 solution. e Charge density differences of structure models (Ti atoms: light blue; O atoms: red; Cd atoms: purple). Yellow and green indicate the gain and loss of electrons, respectively. f DFT-calculated adsorption energies for CH3OH and co-adsorbed CH3OH/H2O on Cd1/A (101), Cd1/R (110), and Cd1/A (101)-R (110).
