摘要

采用电化学原位红外反射光谱和循环伏安法研究了水溶液中2

6-三溴苯酚在Ag电极上的电化学还原脱溴反应。结果表明：Ag电极对2

6-三溴苯酚有较好的电化学还原活性，2

6-三溴苯酚在Ag电极上的电还原脱溴反应是一个脱溴加氢的过程，2

6-三溴苯酚在电极表面首先得到一个电子变成自由基负离子，然后脱去溴离子得到二溴苯酚自由基，该自由基再得到一个电子和氢质子变成二溴苯酚；随后二溴苯酚再依次脱去两个溴得到最终产物苯酚。

Abstract

The electrocatalytic reductive debromination of 2

6-tribromophenol in aqueous solution on Ag electrode was investigated by means of in situ FTIR and cyclic voltammetryAg electrode exhibited a high electrocatalytic activity for the reductive debromination of 2

6-tribromophenol2

6-tribromophenol was electroreduced to its free radical ion initially after receiving an electron

then the free radical ion were further debrominated to produce dibromophenolFinally

phenol was obtained after the Br was debrominated from dibromophenol through the same way.
