English Abstract

A new ferric–manganese doped sulfated zirconia nanoparticle solid acid catalyst was prepared through the impregnation reaction followed by calcination at 600 oC for 3h and characterized by XRD, BET, EDS and TEM tools.

The prepared electrode has been employed as a very sensitive electrochemical sensor through modification of glassy carbon electrode (GCE) with Fe-Mn- SO42-/ZrO2 (FMSZ).

The electrochemical behavior of Ascorbic acid was studied by FMSZ/GC using cyclic voltammetry techniques.

A well-defined oxidation peak was observed in 0.1 M KH2PO4 electrolyte solution by solid phase voltammetry.

Under the CV techniques, it appears that the catalytic effect of the modification of FMSZ/GCE show higher current response as compared to bare GCE.

Peak potential was observed to shift slightly to less positive value by about 220 mV and current was significantly enhanced by about 2.2 folds.
