Glycerol electrooxidation reaction (GEOR) in alkaline media was studied on the Pt(111) electrode with in situ FTIR and electrochemical methods. Cyclic voltammogram profiles display strong electrode deactivation after the first potential scan. Chronoamperometric pulses demonstrate that the deactivation is a result of the reaction intermediates yielded during the faradaic process. In situ FTIR shows evidence that the strongly adsorbed intermediate formed during GEOR is an acyl species which remains present on the surface within the potential window studied.

碱性介质中Pt（111）电极上甘油电氧化的机理

用原位FTIR和电化学方法在Pt（111）电极上研究了碱性介质中的甘油电氧化反应（GEOR）。循环伏安图轮廓在第一次电势扫描后显示强电极失活。计时电流脉冲表明，失活是在法拉第过程中产生的反应中间体的结果。原位FTIR显示证据表明，GEOR过程中形成的强吸附中间体是一种酰基物质，残留在研究的潜在窗口内的表面上。
