The calculated energy band structure diagrams of a pure SnO2 and b as-prepared SnO2/Pdatom based on DFT calculation. The partial density of states (PDOS) for c as-prepared SnO2/Pdatom, and d pure SnO2 based on DFT calculation. The Fourier transformed frequency-resolved complex conductivity from the THZ time domain spectroscopy of e pure SnO2 and f as-prepared SnO2/Pdatom, whose symbols show experimental real (gray solid spheres) and imaginary (red solid circles) conductivities, the solid lines correspond to the fittings with Drude–Smith models. g The as-proposed H2-sensing mechanism on surfaces of SnO2/Pdatom configuration.
