摘　　要：首次用有机溶胶法制备了碳载Pd(Pd/C)催化剂.与液相还原法制备的Pd/C催化剂相比,用有机溶胶法制备的Pd/C催化剂的Pd粒子的平均粒径较小,相对结晶度较低,因此,它对甲酸氧化的电催化活性要比用液相还原法制备的好.It is for the first time to prepare the carbon supported Pd （Pd/C） catalyst with the organic sol method. Because the average size and the relative crystallinity of the Pd particles in the Pd/C catalyst prepared with the organic sol method is smaller and lower than that in the Pd/C catalyst prepared with the liquid phase reduction method, respectively, the electrocatalvtic performance of the Pd/C catalyst prepared with the organic sol method for the oxidation of formic acid is higher than that of the Pd/C catalyst prepared with the liquid phase reduction method.
