| Abstract |
Hydrogen peroxide (H2O2) is widely used as an antibacterial, bleaching, decoloring, and oxidizing agent in various industrial fields. However, the exposure to and accumulation of high levels of H2O2 can cause oxidative stress to humans, leading to caducity and diseases due to its unstable and toxic nature. Moreover, H2O2 is a useful indicator for monitoring reactive oxygen species-related diseases in humans because it is generated as an intermediate product of many enzymatic reactions in normal aerobic metabolism. It is therefore essential to develop accurate and reliable methods of detecting H2O2 for industrial and biological purposes. In this study, ZnO-CNTs were prepared by a sol-gel method and their potential application for non-enzymatic amperometric detection of H2O2 was examined. The modified electrode exhibited good sensitivity and detection range for H2O2 sensing. The enhanced sensing performances can be attributed to the superior electron transport and the large effective surface area resulting from the smaller size and excellent dispersion of ZnO nanoparticles on the CNT. |
