A New Material Based on Nanostructured Prussian Blue Analogue Film Doped with Ce(III) for Development of Hydrogen Peroxide Sensor

Abstract

AbstractPrussian blue analogue nanoparticles doped with Ce(III) (CeHCF) have been synthesized using chitosan (CS) and poly(diallyldimethylammonium chloride) (PDDA) as protective matrix and were cast onto a glassy carbon electrode surface directly. Transmission electron microscopy, UV‐Vis absorption spectroscopy and resonance Rayleigh scattering technique were employed to characterize the PB analogue nanoparticles protected with CS and PDDA. Compared with the bare glassy carbon electrode, the modified electrode exhibited excellent performances for determining H2O2. This work demonstrates the feasibility of the CS‐PDDA‐CeHCF nanoparticles modified glassy carbon electrode for practical sensing applications.
