“…Accordingly, a recent study from this lab reported a procedure for the fabrication of MnOx-MoOx film co-deposited by PD technique and further decoration with Pt nanoparticles for attaining such combination [18]. As consistent with the SEM images, the PD technique has provided homogenous distribution of Pt nanoparticles over dandelion-like structure of mixed metal oxides.…”

“…Transition metal oxides, molybdenum , manganese and vanadium oxides in particular, and their binary and ternary combinations have received much attention recently owing to their remarkable electrocatalytic and electrochromic properties. It was also reported that these properties largely depend on the synthesis procedure and among these techniques; electrodeposition offers an economic and practical way for producing uniform and thin oxide films on the electrode surface .…”

“…This effect has been shown to improve by using binary or ternary oxide films decorated with metallic nanoparticles. As indicated in recent reviews, the electrode surfaces modified with carbon based nanomaterials including carbon nanotubes (CNT), graphene etc., and ionic liquids have been mostly exploited in pursue of the synergic effect for ORR .…”

“…Electrochemical sensors developed by this means can also be applied for sensitive and selective detection of a variety of analytes. Gold nanoparticles have been greatly exploited in biosensor technologies while transition metal oxides have also been employed to construct biosensors over ORR signal change depending on the substrate concentration . Furthermore, ionic liquids (ILs) are becoming popular recently as a potential modifier due to the cation/anion combination in the sensor development .…”

Present study describes the synthesis of mixed oxide films of manganese and vanadium by electrochemical pulsed deposition technique on a glassy carbon electrode (GCE) modified with multiwall carbon nanotubes (MWCNT). The film was further decorated with gold nanoparticles to enhance the reduction signal of dissolved oxygen in pH 5.17 acetate buffer solution. All of the electrochemical synthesized modified electrodes have been characterized with Scanning electron microscopy(SEM), High‐resolution transmission electron microscopy (HRTEM), X‐Ray photoelectron spectroscopy (XPS), X‐Ray diffraction (XRD) techniques. The electrode obtained (AuNPs/MnOx−VOx/CNT/GCE) was utilized as a platform for glucose biosensor where the glucose oxidase enzyme was immobilized on the composite film with the aid of chitosan and an ionic liquid. The electrochemical performance of the biosensor was investigated by cyclic voltammetry and the relative parameters have been optimized by amperometric measurements in pH 5.17 acetate buffer solution. The developed biosensor exhibited a linear range for glucose between 0.1–1.0 mM and the limit of detection was calculated as 0.02 mM.

“…However, the high cost and a limited supply of Pt are limiting factors. The use of nano-scale Pt particles by controlling the morphology and surface structure is, therefore, an effective way for reducing the amount of required Pt and enhancing the electrochemical activity [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ].…”

Fabrication and characterization of a new amperometric chemosensor for accurate formaldehyde analysis based on platinized gold electrodes is described. The platinization process was performed electrochemically on the surface of 4 mm gold planar electrodes by both electrolysis and cyclic voltamperometry. The produced electrodes were characterized using scanning electron microscopy and X-ray spectral analysis. Using a low working potential (0.0 V vs. Ag/AgCl) enabled an essential increase in the chemosensor’s selectivity for the target analyte. The sensitivity of the best chemosensor prototype to formaldehyde is uniquely high (28180 A·M−1·m−2) with a detection limit of 0.05 mM. The chemosensor remained stable over a one-year storage period. The formaldehye-selective chemosensor was tested on samples of commercial preparations. A high correlation was demonstrated between the results obtained by the proposed chemosensor, chemical and enzymatic methods (R = 0.998). The developed formaldehyde-selective amperometric chemosensor is very promising for use in industry and research, as well as for environmental control.
