Synthesis of Cobalt hexacyanoferrate decorated graphene oxide/carbon nanotubes-COOH hybrid and their application for sensitive detection ofhydrazine

Highly sensitive voltammetric and impedimetric sensor based on an ionic liquid/cobalt hexacyanoferrate nanoparticle modified multi-walled carbon nanotubes electrode for diclofenac analysis

“…[30][31][32]. Among the various reagents used for electrode modification, transition metal hexacyanoferrates, a class of polynuclear inorganic compounds, have attracted great attention because they belong to a group of excellent electron transfer mediators [33][34][35][36]. Modification of an electrode surface with these compounds can be achieved by many different methods, including entrapping them in biopolymers [37] and electrodeposition [38].…”

“…CoHCF films can be easily fabricated on various surfaces [37], which make it an obvious candidate for electroanalytical applications such as electron transfer mediator, electrochromic devices and ion selective devices. Up to now, the modified electrodes based on CoHCF have shown good electrocatalytic activity toward a variety of biologically important substrates, such as thiols [34], hydrazine [35], bovine insulin [36], ascorbic acid [39], dopamine epinephrine, and norepinephrine, [40], paracetamol [41], tryptophan [42], and also for fabrication of biosensors [37].…”

An Electrochemical Sensor for Hydrazine Based on <italic>In Situ</italic> Grown Cobalt Hexacyanoferrate Nanostructured Film

“…The use of metal hexacyanoferrates in the form of thin films to enhance the interfacial properties of solid electrodes has been the focus of much interest over the past three decades [5,6]. Such thin solid films are widely used in many applications, such as electrochemical sensors, electrocatalysts, electrochromic display devices, and supercapacitors [7][8][9][10][11]. Furthermore, among various electron transfer media-tors, metal hexacyanoferrates are preferred because their redox reactions can proceed without dissolution of the material, as the ion diffusion maintains charge balance inside the material.…”
