“…KNO 3 was utilized as supporting electrolyte due to the permeability of K + cations within the NiCoNP crystal lattice. Also, its intermediate hydrated ionic radius size favors the diffusion through the porous framework of the NiCoNP as well as its accommodation [29,39,40] …”

“…According to several reports, [27–30] the electrochemistry of transition metal nitroprussides is due not only to the redox character of the molecular block [Fe II (CN) 5 (NO)] 2− but also to the possibility of electron transfer form electroactive transition metals in the outer‐coordination sphere. In addition to, the NO + moiety is a non‐innocent ligand which is susceptible to irreversible reduction, hence the instability of the nitroprusside anion at negative applied potentials (Figure S5) [31–33] .…”

Coordination polymers have received considerable attention in recent years as electrocatalytic materials for the construction of electrochemical sensors. This is due to their high sensitivity and selectivity towards the electrochemical detection of various molecules, particularly pollutants and metabolites, which commonly appear in low concentrations and in complex matrices. In this work, the construction of an electrochemical sensor was performed for the detection of phenylhydrazine, which is a strong pollutant, based on a mixed Ni 2 + Co 2 + transition metal nitroprusside (NiCoNP). NiCoNP was synthesized by chemical coprecipitation, and characterized using Xray diffraction, TGA, and IR and XPS spectroscopies. Its structural characterization indicates that the material was a solid solution, with a cubic Fm � 3m structure and a stoichiometry of Ni 0.59 Co 0.41 [Fe(CN) 5 NO] ⋅ 5H 2 O. The material showed quasireversible electron transfer behavior associated to the charge transfer between the metallic centers of the nitroprusside and the concomitant intercalation of K + ions within the crystal lattice. The sensor based on NiCoNP exhibited a high electrocatalytic activity for the electrooxidation of phenylhydrazine without kinetic limitations, and a wide large linear range (0.5-12 mM), high sensitivity (86.87 μA ⋅ cm À 2 /mM), and LOD of 266 μM. Such device showed a rapid and selective response towards phenylhydrazine. In conclusion, the NiCoNP under study showed a promising electrocatalytic activity for the development of electrochemical sensors.

“…Moreover, the sharp peak of CC/[CoFeÀ NO] at 1940 cm À 1 is attributed to the À NO stretching mode. [37,38] Additional peaks observed for all samples belong to the components present in a typical PB structure. The peak at around 1605 cm À 1 is assigned to the H 2 O bending mode, and the peaks in the 400-Scheme 1.…”

The frequent detection of physiological glucose levels from human blood or sweat requires the development of low-cost electrodes with high sensitivity and selectivity. In this work, we prepared a series of Prussian blue (PB) modified carbon cloth (CC) electrodes with different cyanoferrate groups. We achieved a sensitivity as high as 145.43 μA mm À 1 cm À 2 in a 0.1-6.5 mm concentration range with a response time below 2 s under physiological pH. The electrodes exhibited a superior selectivity of glucose in the presence of interfering agents, including sucrose, lactose, NaCl, ascorbic acid, and uric acid. The electrodes also showed outstanding long-term stability over 15 days. Furthermore, we performed comprehensive electrochemical and characterization studies to elucidate the role of the cyanoferrate group on the morphologic and electronic properties of non-enzymatic glucose sensors.
