Voltammetric determination of epinine using carbon paste electrode modified by ZnO/Al2O3 nanocomposite
We created a ZnO/Al2O3 nanocomposite and used it to modify a carbon paste electrode (ZAO/CPE) for epinine (EPNN) electro-oxidation, as EPNN is a sensitive electroactive material. The results showed a significant improvement in the electron-transfer reaction rate and catalytic performance of the as-produced ZnO/Al2O3 na...
