摘要

在Cu基体上电沉积Ni-W-P合金后, 通过溶胶-凝胶法制备了纳米TiO2修饰Ni-W-P合金电极. 利用扫描电子显微镜(SEM)、X射线衍射(XRD)、阴极极化曲线测试了TiO2/Ni-W-P电极的表面形貌、结构及催化析氢性能, 考察了烧结温度、TiO2膜层厚度对电极结构和性能的影响. 实验结果表明: 550℃下烧结1h、拉膜15次制备的TiO2/Ni-W-P电极光电催化析氢性能最佳, 500W碘钨灯照射下析氢过电位减小约140mV; 此时TiO2为锐态矿型和金红石型混晶结构, 平均晶粒尺寸约7nm.

Abstract

After electrodeposion of Ni-W-P alloy on Cu sheet, nano-crystalline TiO2 film modified Ni-W-P electrode was prepared by a sol-gel method. Scanning electron microscope (SEM), X-ray diffraction (XRD) and cathodic polarization curves were used to characterize the surface morphology, microstructure and catalytic activity for hydrogen evolution reaction (HER) of TiO2/Ni-W-P electrodes. Effects of the sintering temperature and the thickness of TiO2 film on the structure and performance of TiO2/Ni-W-P electrodes were researched. The results clearly demonstrate that the TiO2/Ni-W-P electrode annealed at 550℃ for 1h has the best photoelectrocatalytic activity for HER, and the overpotential for HER decreases about 140mV under illumination. The TiO2 film with average grain size of 7nm is mixed crystal structure containing anatase and rutile crystal phases.

Key words： nano-crystalline TiO2; Ni-W-P; photoelectrocatalytic activity; hydrogen evolution
