摘要： 讨论了中间态粒子(mediator)MnO2和PbO2对肉桂醇电催化反应的影响。由于二者氧化电位的差异,从而改变了肉桂醇氧化反应生成物的组成。以MnO2为中间态粒子时,肉桂醇氧化后的主要生成物是肉桂醛,电流效率高达80%以上。以PbO2为中间态粒子时,肉桂醛将进一步被氧化成肉桂酸,电极反应的选择性明显降低。

Abstract: Lead dioxide and manganese dioxide were used as mediator for indirect oxidation of cinnarnic alcohol on solid polymer electrolyte(SPE)composite electrode prepared by depositing a porous platnium layer on Nafion. When MnO2 was used, cinnamic aldehyde was the main product of oxidatior1 with current efficieny up to 80%。 In the case of PBO2 a further oxidatinn of aldehvde to cinnamic acid and an obvious decrease of reaction selectivity on the electrode were observed.

Key words: solid polynler electrolyte, cinnamic alcohol, electrooxidation, manganese dioxide, lead dioxide
