摘　　要：实验探究了二硫化钼(MoS_(2))作为一种新型材料与贵金属纳米粒子金(Au)、铂(Pt)的复合基底对于过氧化氢(H_(2)O_(2))的还原性检测,采用氧化铟锡导电玻璃(ITO)作为电极,制备出了基于Pt-Au-MoS_(2)-ITO的生物传感器,为H_(2)O_(2)还原性检测的便携性操作打下了基础.实验采用电化学沉积的方法制备材料,同时使用循环伏安(CV)法、计时电流法等传统电化学手段表征了传感器电化学性能,采用场发射扫描电子显微镜(FE-SEM)来表征传感器表面形貌.建立了用于H_(2)O_(2)还原检测的、具有高检测限、高灵敏度和宽检测范围的传感器.The reductive detection method of hydrogen peroxide(H_(2)O_(2))was developed by using a composite of molybdenum disulfide(MoS_(2)),gold(Au)nanoparticles,and platinum(Pt)nanoparticles as the substrate and indium tin oxide(ITO)as the electrode.The constructed biosensor based on Pt-Au-MoS_(2)-ITO laid a foundation for the portable operation of reduction detection of H_(2)O_(2).The electrochemical deposition method was adopted to prepare the electrode material.Traditional electrochemical methods such as cyclic voltammetry(CV)and chronoamperometry(CA)were used to characterize the electrochemical properties of the biosensors and field emission scanning electron microscope(FE-SEM)diagrams were used to characterize the surface appearance of the biosensors.In this work,a biosensor for reduction detection of H_(2)O_(2)with high detection limit,high sensitivity and wide detection range was constructed.
