Abstract
以蔗糖为碳源，Ni-Fe层状双金属氢氧化物为模板和催化剂制备了高度石墨化的介孔炭材料。采用透射电子显微镜(HRTEM)、X射线衍射仪(XRD)和拉曼光谱法(Raman)对产物的形貌和结构进行表征。结果显示该材料具有较高的石墨化程度。采用循环伏安法和脉冲伏安法研究了对苯二酚和邻苯二酚在修饰电极上的电化学行为。结果表明该修饰电极对对苯二酚和邻苯二酚的电化学反应具有显著的催化效果。 Highly graphitic mesoporous carbon was synthesized using sucrose as carbon precursor and Ni-Fe layered hydroxide as template and catalyst. High-resolution transmission electron microscopy, X-ray diffraction and Raman spectroscopy were used to characterize the morphology and structure of the material. The results indicated that the graphitic mesoporous carbon has high degree of graphitization. Moreover, the electrochemical properties of the modified electrode were investigated using cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques. The graphitic mesoporous carbon modified electrode has excellent electrocatalytic activity for the oxidation of hydroquinone (HQ) and catechol (CC), as the result has proved.
