利用沉淀预处理在基底上生长晶种的方法,在氧化铟锡（ITO）导电玻璃表面水热生长出分布均匀、与基底结合牢固、具有较高光电催化分解水制氧性能的ZnO纳米棒.用电助光沉积的方法将电催化剂Ni-Bi与ZnO复合,用扫描电子显微镜（SEM）、X射线衍射（XRD）及紫外可见漫反射光谱对ZnO/Ni-Bi复合光阳极的结构进行了表征,并采用电化学和光电化学技术研究了ZnO/Ni-Bi复合光阳极的光电催化分解水性能,对不同的复合方式、复合时间以及热处理对复合结构催化活性的影响进行了研究.复合Ni-Bi后,ZnO的性能获得了最高40％的提升.光阳极表面沉积的Ni-Bi分离电子空穴抑制其复合,有效地利用了ZnO产生的光生空穴,将水氧化形成氧气,从而显著提高了光照条件下ZnO催化氧化水的效率.

英文摘要：

ZnO nanorods were hydrothermally synthesized on the surface of indium tin oxide glass using precipitate pre-treating method.The ZnO nanorods were uniformly and firmly grown on the indium tin oxide glass and possesed high photoelectrochemical oxygen evolution performance.Then electriocatalysis Nickel-borate were deposited onto the surface of ZnO with electro-assisted photodeposition method.The composite photoanodes were characterized by scanning electron microscopy （SEM）,X-ray diffraction （XRD） and the UV-vis diffuse reflection spectroscopy,and the photoelectrochernical water oxidation properties of ZnO/Ni-Bi composite photoanodes were investigated by electrochemical and photcelectrochemical methods.The effect of deposition methods,deposition time and heat treatment progress to the photoelectrochemical oxygen evolution performance of the ZnO/Ni-Bi composited photoanodes were invesigated.The performance of ZnO is improved for as high as 40％ after coupling with Ni-Bi.The high oxygen evolution activity of the composite photoanodes can be attributed to separation and inhibit of hole-electron recombination by Ni-Bi through facilitating the transfer of photon-induced holes from ZnO for water oxidation.
