| 英文摘要 | ptsnru/c catalysts with different atomic ratios and metal loadings were prepared using a polyol process to improve the performance of direct ethanol fuel cells (defcs). the catalysts were characterized using transmission electron microscopy and x-ray photoelectron spectroscopy. the defc performance was evaluated using a single-cell test. the ethanol electro-oxidation process and anode products were analyzed using in situ fourier-transform infrared spectroscopy (ftirs), gas chromatography, and neutralization titration. the performance of the pt-2 6sn1ru0.4/c catalyst was better than those of the pt3sn1/c and pt2sn1ru1/c catalysts. the carbon-supported pt2.6sn1ru0.4 catalyst with a 60 wt% metal loading gave a maximum power density of 121 mw/cm(2) at 90 degrees c. in situ ftirs and anode product analysis indicated that ethanol was electro-oxidized to acetaldehyde, acetic acid, ethyl acetate, and co2. the ethanol oxidation efficiency on the pt-2 6sn1ru0.4/c catalyst was higher than that on the pt3sn1/c catalyst the activation energy of ethanol electro-oxidation at the anode and surface composition analysis indicated that interactions among the surface elements resulted in a lower apparent activation energy and greater ethanol electro-oxidation efficiency on the pt2.6sn1ru0.4/c catalyst (c) 2014, dalian institute of chemical physics, chinese academy of sciences. published by elsevier b.v. all rights reserved. |
