摘要：

WO3 nano-rods were synthesized on the FTO substrate by hydrothermal method. Pt nanoparticles with different deposition time(40 s,80 s,120 s) was loaded onto WO3 nano-rods by an electrodeposition method to prepare WO3/Pt composite film photoanodes. Characterization of samples was conducted by scanning electron microscopy and X-ray diffraction, the results show that the WO3/Pt composite films have been synthesized. Diffuse reflectance spectra show that the WO3/Pt composite film has more strong absorption than pure WO3 nano-rods film. Electrochemical impedance spectroscopy shows that the WO3/Pt composite film enhances a charge transfer efficiency compared with pure WO3 nano-rods film. The photoelectric properties of the samples were obtained from the photocurrent and the photoelectric catalysis. The WO3/Pt composite film samples have higher photocurrent and photoelectric catalytic(PEC) activity than pure WO3, and the sample obtained by depositing for Pt nanoparticles at 80 s(WO3/Pt-80 s) has the highest photocurrent and photoelectric photoelectric catalytic activity. Meanwhile,the photoelectric catalytic activity of WO3/Pt-80s composite film is higher than direct photocatalysis or electric catalysis of WO3/Pt-80s composite film.
