Fe2TiO5 was synthesized via the solvothermal method and adopted as co-catalyst to improve the photo-electrochemical (PEC) water splitting performance of BiVO4 photoanode. After surface modification by Fe2TiO5 , the BiVO4/Fe2TiO5 photoanode shows a 300 mV cathodic shift in onset potential and 3 times enhancement in photocurrent, which delivers a photocurrent density of 3.2 mA/cm(2) at 1.23 V vs reverse hydrogen electrode. Systematic optical, electrochemical, and intensity-modulated photocurrent spectroscopy Fe2TiO5 were performed to explore the role of Fe2TiO5 and reveal that the enhanced PEC performance is mainly caused by the surface passivation effect of Fe2TiO5.
