摘　　要：采用剥离重组法制备HSr2Nb3O10/MB层状复合材料,并通过XRD,SEM,FT-IR和Zeta电位等表征手段对复合材料的形貌和结构进行分析,采用CV,DPV等电化学手段测定其电化学性质.在pH=7的磷酸缓冲液(PBS)中,所制备的复合材料在抗坏血酸溶液中表现出良好的电催化性质.最后在信噪比为3、抗坏血酸浓度范围为3.115×10^-4~1.168×10^-2mol/L的条件下计算出检测下限为1.428×10^-5mol/L.HSr 2Nb 3O 10 /MB layered composite was prepared by exfoliating/restacking method.The morphology and structure of the composite were characterized by XRD, SEM, FT-IR and Zeta potential.The electrochemical properties of the composite were characterized by CV and DPV.In PBS with pH=7, the composite exhibited good electrocatalytic properties in ascorbic acid solution.Finally, a detection limit of 1.428×10 ^-5 mol/L was obtained in the concentration range of 3.115×10^-4 -1.168×10 ^-2 mol/L at a signal-to-noise ratio of 3.
