摘    要:用液相还原法制备Pd-TiO2/C催化剂。用循环伏安法(CV)和线性扫描法(LSV)考察了催化剂对甲酸的电催化氧化活性。通过计时电流曲线检测催化剂对甲酸的稳定性。结果表明Pd/TiO2/C催化剂中Pd粒子电化学比表面积增大,Pd-TiO2/C催化剂稳定,催化活性比Pd/C催化剂有较大幅度的提高。

关 键 词:直接甲酸燃料电池    二氧化钛  电催化氧化

Abstract:The carbon supported Pd/TiO2/C and Pd/C catalysts were prepared with liquid phase reduction method. The catalysts have been characterized by cyclic voltammetry (CV), linear sweep vohammet.ry (LSV) and Amperometrie i-t techniques. It was found that the electrocatalystic activity of Pd/TiO2/C catalyst was higher than that of Pd/C catalyst for the synergistic effect of TiO2. This is also attributed to the larger electrochemical specific surface area of Pd/TiO2/C.
Keywords:direct formic acid fuel cell  palladium  titanium dioxide  electrocatalytic-oxidation
