| 摘 要： | 利用原位红外光谱证实了当NaClO_4作为支持电解质时,在铂电极上水对甲醇电氧化途径有着重要影响.纯的无水甲醇电氧化时没有CO生成,只有当水的质量分数超过60%时,CO作为甲醇电氧化的中间体的可能性才较大,同时生成CO_2的量也增大.本文试图利用SPAIRS(single potential alteration infrared spectroscopy)技术进一步探讨不同支持电解质

| Abstract: | The electroxidation mechanism of methanol at gold electrode with different sup-porting electrolytes in anhydrous methanol was investigated using In situ FTIR spec-troscopy. It has been proved that the electroxidation pathway and products are dif-ferent for different supporting electrolytes. When NaOH was used as supporting elec-trolyte, the electroxidation products are HCOOCH_3 and HCOO~- ion; moreover, therelative quantities of HCOOCH_3 and HCOO~- produced are affected by tbe concentra-tion of NaOH. When NaClO_4 and TBABF_4 are used as supporting electrolyte, HCOOCH_3and CH_3OCH_2OCH_3 will be the only products. |
