| 摘 要： | 导电玻璃作为基底水热法生长了WO3纳米棒,通过电沉积法改变沉积Pt的时间(40 s,80 s,120 s),以WO3纳米棒为基底沉积得到不同的WO3/Pt复合薄膜样品。通过X射线衍射分析和扫描电子显微镜等测试手段将WO3纳米棒薄膜和WO3/Pt复合薄膜样品进行表征。结果表明成功制备了WO3/Pt复合薄膜样品。漫反射结果显示WO3/Pt复合薄膜与WO3薄膜相比具有更强的光吸收。交流阻抗谱显示WO3/Pt复合薄膜与WO3纳米棒薄膜相比增强了电荷转移效率。利用光电流、光电催化对WO3/Pt复合薄膜进行光电性能测试,结果表明WO3/Pt复合薄膜相较于单一WO3薄膜光电流活性更高和光电催化活性更强,并且沉积时间为80 s的WO3/Pt复合薄膜显示最为优异的光电流和光电催化性能。同时,沉积时间为80 s的WO3/Pt复合薄膜的光电催化性能优于其光催化和电催化性能。

| Abstract: | 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. |
