ZnO/V2 O5纳米管阵列的合成及其光电化学性能研究

摘要

通过简单直接的两步电化学沉积法成功制备了核壳结构的 ZnO／V2 O5纳米管阵列。通过采用 XRD， SEM，TEM和 XPS 等表征手段对这些制备的 ZnO／V2 O5核壳纳米管结构的物相和微结构进行分析。光电化学测试结果表明：ZnO／V2 O5核壳纳米管阵列相比于单一的 ZnO 纳米棒阵列具有明显增强的光电化学性能，使其有望在光解水领域得到广泛的应用。%In this work,ZnO /V2 O5 core /shell nanotube arrays (NTAs)have been successfully synthesized via a simple and two-step electrochemical deposition process.The as-prepared ZnO /V2 O5 samples are characterized by power X-ray diffraction (XRD),scanning electron microscopy (SEM),transmission electron microscopy (TEM)and X-ray photoelectron spectroscopy (XPS).The as-prepared ZnO /V2 O5 NTAs exhibits enhanced photoelectrochemical (PEC)performance compared with pure ZnO nanorod arrays (NRAs),indicating the promising application in photoelectrochemical water splitting.
