a Charge transfer rate constant (ktrans); b charge recombination rate constant (krec); c charge transfer efficiencies extracted from IMPS analysis; d, e transient absorption decays observed at d 600 nm and e 700 nm. The fits for the decays were calculated with three exponential decay model, shown as the solid lines, and the circles represent experimental data; f time-resolved transient absorption spectra of SAs Pt:Fe2O3 when excited with 380 nm; g–i electron trapping, electron detrapping, hole trapping, and charge recombination of g Fe2O3, h NPs Pt/Fe2O3, and i SAs Pt:Fe2O3.
