摘要
通过水热法合成了Ag@Co2O3核壳结构纳米球。通过在GCE上修饰Ag@Co2O3核壳结构纳米球,构建出了一种新型无酶肼(N2H4)电化学传感器。使用扫描电镜和能谱仪对Ag@Co2O3的形貌和化学组成进行了表征。构建的传感器对N2H4的氧化有良好的催化作用。Ag@Co2O3/GCE检测N2H4的线性范围是5.5×10-6~0.87mol·L-1,检出限是1.8×10-6 mol·L-1。建立了一种检测N2H4的新方法,并能拓展核壳结构纳米材料的应用。
Ag@Co2O3 core-shell nano-spheres were synthesized by solvent heating method.A novel non-enzymatic hydrazine chemical sensor was constructed by modifying Ag@Co2O3 core-shell nano-spheres on GCE.The morphology and chemical constitution of the Ag@Co2O3 core and shell were characterized by scanning electron microscopy and energy dispersive spectroscopy.This hydrazine sensor was fabricated to catalyze the oxidation of hydrazine.The linear range of the hydrazine was 5.5×10-6~0.87 mol·L-1,and the detection limit was 1.8×10-6 mol·L-1.This experiment provides a simple method for the detection of hydrazine and can expand the application of core-shell structure nanomaterials.
