层状复合材料亚甲基蓝/α-磷酸锆的合成及其电化学性质探究

Synthesis and Electrochemical Properties of Layered Composite Methylene Blue/α-zirconium Phosphate

采用剥离重组法制备层状纳米复合材料亚甲基蓝/α-磷酸锆(MB/α-ZrP).通过XRD,SEM,Zeta电位,IR等表征手段研究产物的形貌与结构,并采用循环伏安法和微分脉冲伏安法探索其电化学性质.在饱和N2条件下,对抗坏血酸溶液浓度与电流的关系检测可知,随着抗坏血酸溶液浓度的增加,峰电流逐渐增大,峰电位几乎不变,计算得出检测下限为1.9×10-4 mol/L.

A layered nanocomposite MB/α-ZrP was prepared by exfoliation/restacking method.The morphology and structure of intercalated nanocomposites were studied by means of XRD,SEM,Zeta potential and IR.Cyclic voltammetry and differential pulse voltammetry measurements were used to explore the electrochemical property.The relationship between the concentrations of ascorbic acid solution and the current was tested under N2-saturated conditions.With the increase of the concentration of ascorbic acid solution,the peak current increased gradually and the peak potential was almost constant,and the detection limit was calculated to be 1.9×10-4 mol/L.
