Voltammetric detection of potassium ferricyanide mediated by multi walled carbon nanotube titanium dioxide composite modified glassy carbon electrode.
The MWCNT/TiO2 composite was homogeneously coated on the surface of GCE and applied in the electrochemical determination of 0.1 mM potassium ferricyanide in 0.1 M Na2HPO4 (pH 8.5). The redox couple of potassium ferricyanide with current enhancements of 3.0-3.1 folds was obtained using the MWCNT/TiO2...
