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

Abstract

Prussian 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 H 2 O 2. This work demonstrates the feasibility of the CS-PDDA-CeHCF nanoparticles modified glassy carbon electrode for practical sensing applications.

Cerium hexacyanoferrate/ordered mesoporous carbon electrode and its application in electrochemical determination of hydrous hydrazine

“…For example, MnO 2 /MWNTs [22], ZnO/MWCNTs [6], rhodium [14] and Ag-Ni [23] modified electrodes, have been reported for the determination of hydrous hydrazine. Particularly, transition metal hexacyanoferrates (MHCFs) have been used in electrochemistry as electron mediators to transport electrons between analytes and electrodes [24]. Some previous works have been reported about MHCFs to determine hydrous hydrazine, such as nickel hexacyanoferrate (NiHCF) [25] and ruthenium hexacyanoferrate (RuHCF) [26].…”

Nix–Fe(1−x)Fe(CN)6 hybrid thin films electrodeposited on glassy carbon: Effect of tuning of redox potentials on the electrocatalysis of hydrogen peroxide

“…James et al showed that the Prussian blue (PB) modified GC electrode can be converted to CuHCF modified GC completely on cycling in Cu 2+ solution [12]. Electrocatalytic hydrogen peroxide reduction on pure and mixed hexacyanoferrates of Cu, Ce and Pd were reported [13,14]. Bharathi et al prepared mixed analogues of PB-NiHCF and PB-MnHCF mixed metal hexacyanoferrate electrodes [15].…”

Silver–Iron Hierarchical Microflowers for Highly Efficient H2O2 Nonenzymatic Amperometric Detection

“…Development of a stable and efficient as well as selective and sensitive hydrogen peroxide (H 2 O 2 ) sensor is required for both medical and environmental applications, where H 2 O 2 has been associated with many pathological disorders including renal disease, diabetes, cancer, and aging. Also, it is a vital chemical agent commonly involved in industrial, biological, and environmental systems. − Among various H 2 O 2 detection methods (e.g., chemoluminescence, spectrophotometry, chromatography, and electrochemistry − ), electrochemical detecting approaches are still the most effective for H 2 O 2 detection. This is attributed to their unique features including preeminent sensitivity, time efficiency, simple instrumentation, easy operation, and low production cost. − …”
