中文摘要 | the electrocatalytic performances of a vulcan xc-72 carbon black supported pd (pd/xc) catalyst and a macroporous carbon supported pd (pd/mc) catalyst for formic acid oxidation in a direct formic acid fuel cell were investigated and compared. this was carried out using x-ray energy dispersive spectroscopy (eds), x-ray diffraction (xrd) spectroscopy, raman spectroscopy, and electrochemical techniques. the cyclic voltammograms indicate that the main peak potentials for the oxidation of formic acid at the pd/xc and pd/mc catalyst electrodes are similar and they are located at about 0.15 v. however, the peak current density of the pd/mc catalyst electrode is about 30% larger than that of the pd/xc catalyst electrode. the chronoamperometric curves indicate that the peak current density at the pd/mc catalyst electrode at 6000 s is about 38% larger than that at the pd/xc catalyst electrode. these results show that the electrocatalytic activity and stability of the pd/mc catalyst for the oxidation of formic acid are better than those of the pd/xc catalyst. because the average size and relative crystallinity of the pd particles in the two catalysts are similar, the reason for the better electrocatalytic performance of the pd/mc catalyst could be only attributed to its larger pore diameter and higher conductivity because of its high extent of mc graphitization. |
