Electrodeposition of Prussian blue nanoparticles on polyaniline coated halloysite nanotubes for nonenzymatic hydrogen peroxide sensing

Abstract

A facile and effective electrochemical sensing technique was developed by the electrodeposition of Prussian blue on polyaniline (PANI) coated halloysite nanotubes (HNTs). Owing to the special structure of the PB-PANI-HNT nanocomposite, the sensor possessed excellent electrocatalytic ability towards H2O2 reduction. The amperometric study demonstrated that the H2O2 sensor exhibits good performance with a linearity in the range from 4 μM to 1064 μM. The limit of detection (LOD) was 0.226 μM (S/N = 3) and the sensitivity was calculated to be 0.98 μA (μM−1 cm−2). Moreover, the interference from the common interfering species such as glucose, ascorbic acid, dopamine and uric acid can be effectively avoided, and the sensors exhibit long-term stability, thus holding promise for the development of amperometric biosensors.
