摘要: 采用热分解和电沉积方法制备了Ti/Ni/NiO电极, 用循环伏安技术对碱性溶液中环己醇在该电极上的催化氧化进行了初步研究, 重点考察了扫描速度和环己醇浓度等对环己醇氧化的影响. 结果表明, 在碱性溶液中, 环己醇在Ti/Ni/NiO电极上的催化氧化过程遵循电催化机理. 初步认为, NiO首先被氧化为NiOOH, NiOOH再与环己醇发生还原反应生成己二酸和NiO, 因此, NiOOH可作为较好的催化环己醇氧化反应的催化剂.

Abstract: The electrocatalytic oxidation of cyclohexanol on the Ti/Ni/NiO electrode in the alkaline solution was investigated by cyclic voltammetry. The oxidation of cyclohexanol follows the electrocatalytic mechanism. The Ti/Ni/NiO electrode can be used as an effective catalyst for the oxidation of cyclohexanol to adipic acid in basic media.
