A simple chemical route has been applied for the preparation of quasi-spherical silver (Ag) nanoparticles (NPs) with average diameter of 265 and 8 nm. The as prepared products were characterized by powder X-ray diffraction (XRD), transmission electron microscopy (TEM) and UV-vis absorption spectroscopy. Ag NPs immobilized on glassy carbon (GC) electrode showed a superior electrocatalytic activity for the reduction of hydrogen peroxide (H2O2) in aqueous medium. The fabricated electrode was also applied for the amperometric detection of H2O2 and showed a favorable response at an applied potential of -0.5 V (vs. Ag/AgCl). The results demonstrate that the fabricated electrode has potential application for hydrogen peroxide sensor.
一种简单的化学路线已被用于制备平均直径为265和8纳米的准球形银（Ag）纳米颗粒（NPs）。所制备的产物通过粉末X射线衍射（XRD）、透射电子显微镜（TEM）和紫外可见吸收光谱进行了表征。固定在玻碳（GC）电极上的Ag NPs对水性介质中过氧化氢（H2O2）的还原表现出优异的电催化活性。所制备的电极还被用于过氧化氢的安培检测，并在 -0.5 V（相对于Ag/AgCl）的施加电位下显示出良好的响应。结果表明，所制备的电极在过氧化氢传感器方面具有潜在的应用。
