摘要

利用湿化学法在FTO玻璃基底上制备了高度规整的ZnO纳米棒阵列（ZnO NRAs），以此为衬底，采用磁控溅射法在ZnO NRAs表面沉积Cu

O薄膜。分别用X射线衍射仪、X射线光电子能谱、扫描电镜、光致光谱、紫外可见分光光度计和电化学工作站对样品的物相、形貌、吸收光谱、光电性能进行了表征，用甲基橙（MO）模拟有机物废水研究复合材料的光催化性能。结果表明：ZnO纳米棒为六方纤锌矿结构，其直径约为80~100 nm，长约2~3 m，棒间距约100~120 nm。立方晶系的Cu

O颗粒直径约为100~300 nm，形成致密膜层并紧密覆盖在ZnO NRAs表面上，构成ZnO/Cu

O HNRAs）结构。与纯ZnO NRAs和Cu

O相比，ZnO/Cu

O HNRAs在可见光范围内的吸收显著增强，吸收波长向可见光方向偏移。ZnO/Cu

O HNRAs的载流子传递界面的电荷转移速度快，有效促进了光生电子和空穴的分离。在紫外-可见光照射65 min后， ZnO/Cu

Abstract

ZnO nanorod arrays (ZnO NRAs) on FTO-glass substrates were prepared by chemical method

then Cu

O film was deposited on ZnO NRAs surface by using magnetron sputtering method. The crystal phase

morphology

UV-Vis absorbance spectra and photoelectric property were characterized by X-ray diffraction

X-ray photoelectron spectroscope

scanning electron microscopy

photoluminescence spectroscopy

UV-Vis spectrophotometer and electrochemical workstation

respectively. The photocatalytic activity was evaluated by the photocatalytic degradation of methyl orange (MO) under UV-Vis light irradiation. The results show that ZnO NRAs are wurtzite structure phase with diameter of 80-100 nm

length of 2-3 m

and rod interval distance of 100-120 nm. Cu

O particles are the cubic phase with grain diameter of 100-300 nm and form a dense membrane layer on ZnO NRAs

which constitutes ZnO/Cu

O heterojunction nanorod arrays(ZnO/Cu

O HNRAs) structure. Compared with pure ZnO NRAs and Cu

O film

the absorption intensity in the visible region of ZnO/Cu

O HNRAs is significantly enhanced and the absorption wavelength redshifts. The charge transfer speed on the carrier transmission interface of ZnO/Cu

O HNRAs is faster

contributing to the separation of photoelectrons from hole. Irradiated under UV-Vis light for 65 min

the MO degradation efficiency of ZnO/Cu

O HNRAs is 94%

18 times than that of pure ZnO NRAs and 1.7 times than that of pure Cu

O film.
