Sensitive and accurate determination of a small quantity of hydrogen peroxide (H2O2) is of great importance in environmental analysis. In this article, a novel strategy for fabrication of H2O2 sensor was developed by electrodepositing silver nanoparticles (Ag NPs) on a DNA–multiwalled carbon nanotubes (DNA-MWCNTs) composites–modified glassy carbon electrode. Experimental results showed that the constructed electrode had an excellent catalytic ability for the reduction of H2O2, suggesting that it could be used as a sensor to detect H2O2. The good catalytic activity was ascribed to the DNA-MWCNTs composites that resulted in the formation of small Ag NPs and homogenous distribution of these Ag NPs. The sensor showed a high sensitivity, wide linear range, and good stability, and thus it could be used as an ideal tool in environmental engineering.
