【摘要】 采用直接电化学合成技术制备了苯并三氮唑(BTAH)在铜、银、铁、锌、镍等电极表面上的表面配合物,并进行了拉曼光谱表征。研究发现三苯基膦(pph3)对BTAH的表面配位过程产生明显的影响。在铜和银表面pph3影响了具有缓蚀效应的表面膜的形成,而对铁、锌、镍电极,pph3并不出现在最终配合物中, 不管其是否存在,表面最终生成聚合物形式膜。更多还原

【Abstract】 The surface coordination chemistry of benzotriazole (BTAH) at copper, silver, iron, zinc and nickel electrodes was investigated by in situ electrochemical synthesis in the acetonitrile solution and normal Raman spectroscopy. The influence of the neutral ligand of triphenylphosphine (pph3) on the film formation process of BTAH was investigated. The ligand of pph3 participated in coordination processes of BTA anion with Cu and Ag, while no influence of pph3 on the final products was observed in the system of BTAH with Fe2+ , Ni2+ or Zn2+.更多还原
