摘要	Ti-ZnFe2O4 photoanode has attracted extensive attention in photoelectrochemical (PEC) water oxidation due to its narrow band gap and good photostability. However, its low efficiency limits its development. Herein, we designed and constructed direct Z-scheme Ti-ZnFe2O4/In2O3 (Ti-ZFO/In2O3) photoanode. Under the interface electric field, photogenerated holes with stronger oxidation capacity on In2O3 are retained to participate in the water oxidation reaction, and the photocurrent density of Ti-ZFO/In2O3 is much higher than that of pure Ti-ZFO, reaching 2.2 mA/cm2 at 1.23 V vs. RHE. Kelvin Probe, steady-state photovoltage spectroscopy (SPV), transient photovoltage spectroscopy (TPV) and in-situ double beam strategy were used to demonstrate the Z-scheme charge transfer mechanism of Ti-ZFO/In2O3 photoanode. Our work provides an effective scheme and technical means for further understanding the mechanism of interfacial charge transfer.
