Abstract
Ti-doping hematite photoanode was investigated by easily spray pyrolysis method using self-made spray coating system. Doping with titanium can improve the photoelectrochemical performance of the pure α-Fe2O3 thin films. The key point is the effect of Ti doping on improving the conductivity and enhancing charge transfer. When doped with Ti element, Vfb of hematite film shifts negtively about 50 mV, which is good for the hydrogen evolution in the water splitting process. The best IPCE of Ti-doped hematite photoanode reaches 30% under 0.3 V bias at 400nm, ultimately.
