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/V2O5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/V2O5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/V2O5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.
