摘    要:通过电沉积修饰铂微粒制备Ti基纳米TiO2-Pt(Ti/nano-TiO2-Pt)修饰电极,采用循环伏安法研究了乙二醛在Ti/nano-TiO2-Pt上的电催化氧化。结果表明:Ti/nano-TiO2-Pt修饰电极对乙二醛的氧化呈现较高的电催化活性,可作为乙二醛电氧化合成乙醛酸的高活性催化电极。

关 键 词:Ti/nano-TiO2-Pt电极  电氧化  电催化  乙二醛  乙醛酸

Abstract:The nano-TiO_2 film loaded Pt nanoparticle electrode(Ti/nano-TiO_2-Pt)was achieved by cyclic voltammetry electrodeposition.The electrocatalytic oxidation of glyoxal was investigated on Ti/nano-TiO_2Pt electrode by using cyclic voltammetry.The results showed that the Ti/nano-TiO_2-Pt modified-electrode exhibited significant electrocatalytic activity for the oxidation of glyoxal,and utilized as high activity catalytic electrode for electrooxidation of glyoxal to glyoxalic acid.
Keywords:Ti/nano-TiO_2-Pt electrode  electrooxidation  electrocatalysis  glyoxal  glyoxalic acid
