摘　　要：用简单的化学沉积法制备了碳载Pt(Pt/C)和碳载Pt-TiO2(Pt-TiO2/C)催化剂。研究发现无论是25℃还是60℃与Pt/C电极相比,乙醇在Pt-TiO2/C电极上的起始氧化电位及氧化峰电位均比在Pt/C电极上负移。而在中性溶液中,乙醇在Pt-TiO2/C电极上的氧化峰电流密度比并在Pt/C催化剂有一定程度的增大。The Pt- TiO2/C and Pt/C catalysts were prepared a simple method of chemical deposition. It is found that in the acidic solution the onset potential and peak potential of ethanol electro - oxidation on the Pt - TiO2/C catalyst are more negative than on Pt/C catalyst compared with Pt/C catalyst either at the temperature of 25℃ or 60℃. While in neutral solution the peak current of ethanol electro - oxidation was higher on Pt -TiO2/C electrode than on Pt/C electrode.
