Abstract

Tungsten trioxide (WO3) is one of the photocatalysts with a high potential for application in water splitting reaction to produce hydrogen gas. In this paper, different compositions of nickel-doped WO3 thin films on fluorine-doped tin oxide (FTO) glass were produced from tungstic acid and nickel(II) acetate. After annealing at 500°C for 30 min, the thin films were characterized using SEM, XRD, UV-Vis spectrophotometer and photoelectrochemical (PEC) test. Ni-doped WO3 exhibited an increased grain size compared to undoped WO3 and adopted a monoclinic structure. Optical band gaps calculated with Tauc formula from UV-Vis absorption data showed a reduction in band gap for Ni-doped WO3. Under the irradiation of xenon lamp, the efficiency of hydrogen production by nickel-doped WO3 thin films were improved. Copyright Reserved
