oxidation of methanol on Pt catalysts YUAN Xu(袁旭), YUE Wen-bo(岳文博), ZHANG Jin(张锦) Beijing Key Laboratory of Energy Conversion and Storage Materials, College of Chemistry,Beijing Normal University, Beijing... electrocatalytic activity towards methanol oxidation than Pt catalysts on rGO. The outstanding catalytic properties of Pt catalysts on EEG can be attributed to the fast electron transfer through EEG and high......
undergoes a four-electron process to water. Since Pd-Co-Au/C catalysts are inactive for the adsorption and oxidation of methanol, thus, they can be used as a new type of promising catalyst for methanol-tolerant ORR in a direct methanol fuel cell. Key words: Pd alloy; nanoparticle; oxygen reduction reaction; electrocatalysis; methanol tolerance 直接甲醇燃料电池(DMFC)具有能量密度高,燃料来源丰富,储存与运输时安全性好,低污染,高能量转换效率和对价格的承受......
