| 摘 要： | 采用聚合络合法（PCM）制备出钴掺杂二氧化钛（CO/TiO2）光催化剂.以热重-差示扫描量热同步热分析（TGA-DSC）,傅里叶变换红外（FT-IR）光谱,X射线粉末衍射（XRD）,氮气吸附-脱附,紫外-可见漫反射光谱（UV-Vis DRS）,X射线光电子能谱（XPS）等手段对材料进行了表征.采用光催化制氧作为探针反应,以氧气的产量评价材料的光催化性能结果表明:采用聚合络合法制备的样品主体成分为锐钛矿晶型的二氧化钛,钴元素呈高度分散,钴的掺杂能够明显提升二氧化钛光催化材料的光催化制氢活性,当钴钛物质的量之比为0.3%时,催化剂具有最佳的光催化制氢活性,达到2499μmol,是同等条件下制备的无掺杂二氧化钛的近六倍.还对钴离子掺杂增强机理进行了探讨.

| Abstract: | Cobalt-doped titania(Co/TiO_2) photocatalysts were synthesized by the polymerized complex method(PCM).The materials were characterized by thermogravimetric analysis-differential scanning calorimetry(TGA-DSC),Fourier transform-infrared spectroscopy(FT-IR),X-ray diffraction(XRD),nitrogen adsorption-desorption,ultraviolet-visible diffuse reflectance spectroscopy(UV-Vis DRS) and X-ray photoelectron spectroscopy(XPS).The photocatalytic activity of the samples was evaluated by hydrogen evolution.The results show ... |
