Copper-cobalt bimetal nanoparticles (Cu-Co) have been electrochemically prepared on glassy carbon electrodes (GCEs), which were electrodeposited with conducting polymer nanocomposites of poly(3,4-ethylenedioxythiophene) (PEDOT) doped with carbon nanotubes (CNTs). Owing to their good conductivity, high mechanical strength, and large surface area, the PEDOT/CNTs composites offered excellent substrates for the electrochemical deposition of Cu-Co nanoparticles. As a result of their nanostructure…

Poly(3,4-ethylenedioxythiophene) doped with engineered carbon quantum dots for enhanced amperometric detection of nitrite

An electrochemical sensor for nitrite was fabricated by modifying a glassy carbon electrode with the conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT) that is doped with carbon quantum dots (CQDs) that displays excellent electrocatalytic activity towards the oxidation of nitrite.

Amperometric sensing of nitrite using a glassy carbon electrode modified with a multilayer consisting of carboxylated nanocrystalline cellulose and poly(diallyldimethyl ammonium) ions in a PEDOT host

Electrospun CuO/NiO composite nanofibers for sensitive and selective non-enzymatic nitrite sensors

A non-enzymatic electrochemical sensor based on the use of nanofibrous CuO/NiO as a catalytic probe was developed for the effective sensing of nitrite. One dimensional and strongly interconnected

Nitrogen-doped-carbon-coated hexagonal cobalt oxyhydroxide/reduced graphene oxide nanocomposite for sensitive and selective detection of nitrite in human hepatoma cells

A novel nitrite sensing platform was built based on the fabrication of nitrogen-doped-carbon-coated hexagonal cobalt oxyhydroxide (CN@CoOOH) on reduced graphene oxide (RGO) using zeolitic imidazolate framework (ZIF)-67 as a precursor to detect nitrite selectively and sensitively through amperometry for the first time.

A Cu(II)-MOF Based on a Propargyl Carbamate-Functionalized Isophthalate Ligand as Nitrite Electrochemical Sensor

This paper investigates the electrochemical properties of a new Cu(II)-based metal-organic framework (MOF) built upon a linker containing the propargyl carbamate functionality and immobilized on a glassy carbon electrode by drop-casting and found that GC/Au/Cu-YBDC exhibited a better electrocatalytic behavior toward the oxidation of nitrite.



Nanocomposite and nanoporous polyaniline conducting polymers exhibit enhanced catalysis of nitrite reduction.

Nanostructured polyaniline conducting polymer films prepared on electrochemically pretreated glassy carbon electrodes exhibited enhanced electrocatalytic behaviour towards the reduction of nitrite relative to bulk-PANI films; however, partial collapse or shrinkage may have occurred with the removal of the nanoparticles and could have resulted in a less enhanced response.

Electrocatalytic oxidation of glucose on Ni and NiCu alloy modified glassy carbon electrode

Nickel and nickel–copper alloy modified glassy carbon electrodes (GC/Ni and GC/NiCu) prepared by galvanostatic deposition were examined for their redox processes and electro-catalytic activities

Poly(3,4-ethylenedioxythiophene)-multiwalled carbon nanotube composite films: structure-directed amplified electrochromic response and improved redox activity.

Electrochemical investigations on devices based on PEDOT-MWCNT and control P EDOT films established the practical utility of PEDot-MWcNT films as they show lower charge-transfer resistance, higher diffusional capacitance, and a much smaller amplitude of impedance as compared to control PED OT films.
