a, b HAADF-STEM images of the phase interface in P25. c Low-temperature EPR spectra acquired after UV light illumination at 20 °C in the presence of 2, 4, 6-trichlorophenol. d Theoretic structure models of A (101)-R (110) (upper) and Cd1/A (101)-R (110) interfaces (lower). e Binding energies of Cd atoms on the A (101), R (110), and A (101)-R (110) facets. f Correlative effects of N2 calcination temperature, maximum interface density, and H2 production rate (Inset shows the interface model). g HAADF-STEM images of 5Cd/P25 catalysts after H2 pretreatment at 500 °C for 4 (left) and 8 (right) h. h Correlations among maximum interface density, H2 production rate, and Cd loss rate following H2 pretreatment.
