dc.description.abstractPtRu/C electrocatalysts (Pt:Ru atomic ratio of 50:50 and 80:20) were prepared using citric acid as reducing agent and OH- ions as stabilizing agent. The obtained electrocatalysts were characterized by energy dispersive X-ray analysis and transmission electron microscopy. The electro-oxidation of methanol and ethanol were studied at room temperature by chronoamperometry. Studies on the Direct Methanol Fuel Cell (DMFC) and Direct Ethanol Fuel Cell (DEFC) were carried at 90°C. For both electrocatalysts the obtained Pt:Ru atomic ratios were similar to the nominal ones and the average particles sizes were around 2.5 nm. The chronoamperometry and DAFC experiments showed that the electrocatalyst prepared with Pt:Ru atomic ratio of 80:20 has a superior performance for methanol oxidation, while the electrocatalyst prepared with Pt:Ru atomic ratio of 50:50 has a superior performance for ethanol oxidation.
