Embodiment 1
[0071] (1) Prepare the substrate used for preparing the titanium-doped α-iron oxide photoanode, cut it into a size of 2cm*4cm, and clean it with isopropanol, acetone, ethanol and water in sequence. After the FTO was cleaned and dried, the back-to-back and vertical inner substrate surface (FTO's SnO 2 Facing the lining wall) placed on the PTFE lining. Add 0.54058g FeCl to 20mL aqueous solution 3 ·6H 2 O, and 0.36036gNH 2 CONH 2 , stirred for 60min. The stirred solution was poured into the polytetrafluoroethylene lining, and then the polytetrafluoroethylene lining was placed in an autoclave and sealed, and heated at 70° C. for 6 hours in a blast drying oven. After hydrothermal treatment, a light yellow translucent β-FeOOH film grew on the FTO. The β-FeOOH film was cleaned with deionized water and dried with nitrogen.

Embodiment 3
[0083] (1) Prepare the substrate used for preparing the titanium-doped α-iron oxide photoanode, cut it into a size of 2cm*4cm, and clean it with isopropanol, acetone, ethanol and water in sequence. After the FTO was cleaned and dried, the back-to-back and vertical inner substrate surface (FTO's SnO 2 Facing the lining wall) placed on the PTFE lining. Add 5.4058g FeCl to 40mL aqueous solution 3 ·6H 2 O, and 3.6036g NH 2 CONH 2 , stirred for 50min. The stirred solution was poured into the polytetrafluoroethylene lining, and then the polytetrafluoroethylene lining was placed in an autoclave and sealed, and heated at 80° C. for 6.5 hours in a blast drying oven. After hydrothermal treatment, a light yellow translucent β-FeOOH film grew on the FTO. The β-FeOOH film was cleaned with deionized water and dried with nitrogen.
