Iron(III) oxide adsorbed multiwalled carbon nanotube modified glassy carbon electrode as a precursor for enhanced Prussian blue formation and selective hydrogen peroxide sensing

- A new MWCNT-Fe2O3-Prussian blue hybrid electrode is developed.
- Improved in electroanalytical performance over the conventionally prepared PB systems.
- Synergistic effect of Fe2O3, MWCNT and PB was noticed.
- Used as a selective sensor to detect H2O2 in milk, cosmetic and clinical samples.
