摘要：

通过溶胶凝胶和电沉积法制备了SnO₂掺杂的钛基纳米TiO₂-Pt（nano-TiO₂-Pt）复合纳米催化剂。XRD和SEM的研究结果表明，SnO₂的掺杂改变了TiO₂的结构。通过对它们的电化学性质的比较发现，SnO₂的掺杂使nano-TiO₂-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。

Abstract:

The nano-TiO2-SnO2-Pt complex catalysts were prepared by sol-gel and electrodeposited methodThe catalyst was characterized using XRD and SEMThe results showed that the structure of TiO₂ particles was improved by adulterating SnO₂Performances of the catalysts for ethanol oxidation were investigated by using cyclic voltammograms and chronoamperometricAccording to the comparison of the electrocatalytic performance，it was found that the catalytic activity and stability of the nano-TiO₂-SnO₂-Pt complex catalysts are higher than those of nano-TiO₂-Pt catalyst.
