用两步水热法合成了TiO2/Pt复合纳米材料,并用TEM、XRD、EDS、BET、Zeta电位和EIS对TiO2/Pt复合纳米材料的形貌、晶体结构、成分及其物理和化学性质进行了表征。结果表明:与纯的TiO2纳米材料相比,TiO2/Pt复合纳米材料具有不同的物理和化学性质如晶体结构、比表面积、表面电荷性质和电子转移性质,而且随着Pt掺杂量的变化,这些物理和化学性质呈现规律性的变化。
The TiO2 / Pt nanocomposites were synthesized by two steps hydrothermal method. The morphology, crystal structure, composition, physical and chemical properties of TiO2 / Pt nanocomposites were characterized by TEM, XRD, EDS, BET, Zeta potential and EIS Characterization. The results show that TiO2 / Pt composite nanomaterials have different physical and chemical properties such as crystal structure, specific surface area, surface charge properties and electron transfer properties compared with pure TiO2 nanomaterials. With the variation of Pt doping content, These physical and chemical properties show a regular change.
