通过溶胶凝胶和电沉积法制备了SnO_2掺杂的钛基纳米TiO_2-Pt(nano-TiO_2-Pt)复合纳米催化剂。XRD和SEM的研究结果表明,SnO_2的掺杂改变了TiO_2的结构。通过对它们的电化学性质的比较发现,SnO_2的掺杂使nano-TiO_2-Pt复合纳米催化剂的电化学活性表面积增加,常温常压下对乙醇的电化学氧化电位负移,氧化能力明显提高。
SnO 2 -doped titanium-based nano-TiO 2-Pt nano-TiO 2 composite catalysts were prepared by sol-gel method and electrodeposition method. The results of XRD and SEM show that the doping of SnO 2 changes the structure of TiO 2. Through the comparison of their electrochemical properties, it is found that the electrochemical activity of nano-TiO_2-Pt nanocomposite increases with the doping of SnO_2, and the electrochemical oxidation potential of ethanol is negatively shifted at room temperature and normal pressure.
