| 摘 要： | 运用电化学原位ＦＴＩＲ反射光谱研究了１,３－丁二醇在以Ｓｂ和Ｓ修饰的Ｐｔ电极上的氧化过程。结果表明Ｓｂ和Ｓ修饰都能抑制１,３丁醇的解离吸附。红外数据指出Ｓｂ的存在使１,３丁二醇氧化产物同时含有羰基物种和ＣＯ２,而Ｓ修饰的Ｐｔ电极上以羧酸物种为主。

| Abstract: | In the present paper,we studied the surface st ru cture effect of Pt electrode modified with antimony and sulfur adatoms towards 1 ,3-Butanediol oxidation.The results demonstrated that the modification of Sb an d S both inhibited the dissociative adsorption of 1,3-Butanediol into CO,which is the main source of self-poisoning in electrocatalysis of small organic molec ules.At lower potentials,the principal oxidation pathway of 1,3-Butanediol on P t/Sb ad electrode is towards the production of C=O.However,at higher potent ials,the products of CO 2 increased.The presence of S ad inhibited the ox idation of 1,3-BD at low potentials(<0 8 V),and yield mainly acid species as products at higher potentials(>0 8 V). |
