Preparation and characterization of ruthenium oxide/hexacyanoferrate and ruthenium hexacyanoferrate mixed films and their electrocatalytic properties

Electrochemical determination of L-dopa at cobalt hexacyanoferrate/large-mesopore carbon composite modified electrode

“…As a group of useful electron-transfer mediators, they have been widely used in electrochemistry to detect some biomolecules [22][23][24]. Cobalt hexacyanoferrate (CoHCF) is an attractive model material among the metal hexacyanoferrates because of its interesting chemical and electrochemical properties.…”

Hydrogen peroxide monitoring in Fenton reaction by using a ruthenium oxide hexacyanoferrate/multiwalled carbon nanotubes modified electrode

“…The anodic and cathodic peaks correspond to electrodic processes involving the material immobilized on the electrode surface. Accordingly, the redox activity of the ruthenium oxide hexacyanoferrate films is based on the electron transfer processes involving the Ru(II)/Ru(III), Ru(III)/Ru(IV) and Fe(II)/Fe(III) couples [25]. A significant enhancement of the current is observed during the electrodeposition of the RuOHCF film relative to that in the voltammograms of a bare GC electrode (voltammograms not shown) [26], which reflects the increased surface area provided by the carbon nanotubes [23].…”

A novel cobalt hexacyanoferrate nanocomposite on CNT scaffold by seed medium and application for biosensor

“…In Fig. 4A curve b, there are two sets of distinct redox peaks with the formal potentials (E • = [(E p,a + E p,c )/2]) of about 0.41 and 0.86 V, which attribute to the characteristic electrochemistry of cobalt hexacyanoferrate [14]. The wave around 0.2 V is thought to be the CNTs' background which is not overwhelmed by the peak of CoNPs.…”

“…II Fe III (CN) 6 /NaCo 1.5 II Fe II (CN) 6 and NaCo II Fe III (CN) 6 /Na 2 Co II Fe II (CN) 6 , respectively. According to the previous reports [14,43,44], the redox reactions with the involvement of Na + can be expressed as follows:…”

“…As a group of excellent electron-transfer mediators these inorganic polymers have been widely used in electrochemistry to electrocatalyze the oxidation of guanine, DNA, deoxyguanosine, dopamine, ascorbic acid, NADH, glutathione, cysteine and H 2 O 2 [14][15][16][17][18][19][20] and the reduction of Fe 3+ , CO 2 and hydrazine [21][22][23]. Among the hexacyanoferrates, cobalt hexacyanoferrate (CoHCF) would be especially attractive because of its interesting chemical and electrochemical properties [24][25][26][27].…”
