A novel strategy to fabricate hydrogen peroxide (H(2)O(2)) sensor was developed by electrodepositing Ag nanoparticles (NPs) on a glassy carbon electrode modified with natural nano-structure attapulgite (ATP). The result of electrochemical experiments showed that such constructed sensor had a favorable catalytic ability to reduce H(2)O(2). The good catalytic activity of the sensor was ascribed to the ATP that facilitated the formation and homogenous distribution of small Ag NPs. The resulted sensor achieved 95% of the steady-state current within 2s and had a 2.4 μM detection limit of H(2)O(2).
一种新颖的策略被开发出来用于制备过氧化氢（H₂O₂）传感器，即将纳米银颗粒（AgNPs）电沉积在经天然纳米结构凹凸棒土（ATP）修饰的玻碳电极上。电化学实验结果表明，该构建的传感器对过氧化氢（H₂O₂）具有良好的催化还原能力。传感器的良好催化活性归因于 ATP，它促进了小 AgNPs 的形成和均匀分布。所得传感器在 2s 内达到稳态电流的 95%，H₂O₂的检测限为 2.4μM。
