摘要

采用电化学原位红外光谱技术，研究了苯酚在Pt电极表面的电化学氧化机理。在0.1 mol/L Na

溶液中，Pt电极上电化学氧化苯酚的反应电位为+0.9~1.0 V（

SCE）、析氧电位为+1.3 V；电化学原位红外光谱结果表明，当电位

0.9 V时，苯酚氧化产物主要为苯二酚、醌及少

量醇类物质；电位0.9~1.1 V时，苯环结构被破坏，氧化产物主要为酮、酸、醇和CO

；根据官能团吸收峰的变化，苯酚在Pt电极表面氧化经历如下途径：苯酚→苯二酚→苯醌→酮、醇、酸→CO

。同时研究了NH

对苯酚在Pt电极表面的电氧化的影响，结果表明在低电位区（

0.9 V）对苯酚氧化构成竞争。

Abstract

The electrochemical oxidation mechanism of phenol on the surface of Pt electrode was studied by electrochemical

in situ

spectroscopy. In 0.1 mol/L Na

solution

the reaction potential of electrochemical oxidation of phenol on Pt electrode is +0.9—1.0 V (

SCE)

and the oxygen evolution potential is +1.3 V.

In situ

infrared spectroscopy showed that electrode potential had a great influence on oxidation behavior of phenol. When the potential was lower than 0.9 V

the main intermediates of phenol oxidation were dihydroxyhenzene

quinone and a few alcohols. When the potential was controlled between 0.9 V and 1.1 V

the structure of benzene ring was destroyed

and the main intermediates were ketones

acids

alcohols and CO

. According to the changes in absorption peak of functional group

phenol oxidation on the platinum electrode surface was as follows: phenol

dihydroxyhenzene

quinone

ketone

alcohol

acid and CO

. The potential of ammonia oxidation on the platinum electrode surface was + 0.5 V

which indicated that ammonia in competition with phenol oxidation in the low potential region (

0.9 V).
