Noncovalent nanohybrid of ferrocene with single-walled carbon nanotubes and its enhanced electrochemical property

The nanoscale hybridization adduct of ferrocene (Fc) and single-walled carbon nanotubes (SWNTs) was prepared and it shows high stability and greatly enhanced sensitivity toward hydrogen peroxide reduction. The electrochemical and hydrolysis results suggest that the strong π-π stacking interaction between Fc and SWNTs play a critical role for its enhanced electrochemical catalytic property. The combined advantages from SWNTs and Fc and the cooperative effect due to this π-π stacking could make this adduct an excellent choice for ultrasensitive electrochemical detections.
