构建了一种复合光催化剂，即Ag/AgI纳米颗粒装饰的WO3预掺杂TiO2纳米管阵列，其在可见光诱导下表现出增强的催化活性。该复合结构通过三步法制备，包括电化学阳极氧化、湿法浸渍和光辅助还原。通过X射线衍射、X射线光电子能谱、场发射扫描电子显微镜、透射电子显微镜和紫外-可见(UV-vis)漫反射光谱对所制备的材料进行了表征。结果表明，沉积WO3物质和Ag/AgI纳米颗粒后，TiO2纳米管（TNT）的吸收范围可以从紫外光范围扩展到可见光范围。与TNTs、WO3/TNTs和Ag/AgI−TNTs相比，Ag/AgI修饰的WO3/TNTs(Ag/AgI/WO3@TNTs)在可见光(λ≥420 nm)照射下对氢醌的降解表现出更高的光催化活性。
A composite photocatalyst, Ag/AgI nanoparticles decorated WO3pre-dopedTiO2nanotube arrays, were constructed, which showed enhanced catalytic activity induced by the visible light. The composite structure was fabricated by a three-step method, including electrochemical anodization, wet impregnation and photo-assisted reduction. The as-prepared materials were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, field-emission scanning electron microscopy, transmission electron microscopy and ultraviolet-visible (UV–vis) diffuse reflectance spectroscopy. The results revealed that the absorption range of the TiO2nanotubes (TNTs) could be extended from ultraviolet to visible light range after the deposition of WO3species and Ag/AgI nanoparticles. Compared with the TNTs, WO3/TNTs and Ag/AgI−TNTs, the WO3/TNTs decorated with Ag/AgI(Ag/AgI/WO3@TNTs) showed much higher photocatalytic activity in the degradation of hydroquinone under visible light (λ≥420 nm) irradiation.
