Synthesis and Characterization of Co3O4 Nanotubes to Prepare Variety of Electrochemical Biosensors

Cobalt (II) Chloride was used as a precursor to prepare Co3O4 nanotubes in reverse micelles. Tween 80 was added as surfactant. The products were characterized by Xray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy. The diameter of Co3O4 nanotubes was about 58 nm and the average length of them was around 261 nm. The study provides a simple and efficient route to synthesize Co3O4 nanotubes at room temperature. Tremendousdemands for electrochemical biosensors with high sensitivity and reliability, fast response and excellent selectivity have stimulated intensive research on developing versatile materials with ultrahigh electrocatalytic activity
