This work describes the facile synthesis of silver nanoparticle-decorated zinc oxide nanocomposite through a simple glycol reduction method. The silver nanoparticle-decorated zinc oxide nanocomposite-based pencil graphite electrode has been validated as a perceptive electrochemical sensing podium towards nitrite. The morphology of the prepared nanocomposite has been characterized via specific spectroscopic and electrochemical techniques. The sensor exhibits a notable enhancement in the cyclic voltammetric response to nitrite oxidation at an ideal peak potential of 0.76 V in pH 6.0 acetate buffer. Under optimum conditions of nitrite directly expanded with their concentration in the range from 30 to 1400 μM with a detection limit of 14 μM.

这项工作描述了通过简单的乙二醇还原方法轻松合成银纳米颗粒修饰的氧化锌纳米复合材料。银纳米粒子修饰的氧化锌纳米复合材料基铅笔石墨电极已被验证为可感知亚硝酸盐的电化学感应讲台。制备的纳米复合材料的形态已通过特定的光谱和电化学技术进行了表征。该传感器在pH 6.0乙酸盐缓冲液中的理想峰值电位为0.76 V时，对亚硝酸盐氧化的循环伏安响应显示出显着增强。在最佳条件下，亚硝酸盐的浓度在30至1400μM范围内直接膨胀，检测极限为14μM。
