Films of conductive coordination network compounds are interesting as functional materials for charge storage, electrocatalysis, electrochromic switching, or conversion of light. The electrical conductivity depends on not only intrinsic material properties but also grain boundaries. Copper hexacyanoferrate shows a remarkable variation in film morphologies depending on the preparation route. Conductive films can only be obtained for continuous crystalline films that have been received by a combination of sonication-assisted casting and vapor-assisted conversion. Electrical conductivities of these films are higher than those of powder pellets with a similar crystal structure. Temperature-dependent and humidity-dependent measurements on powder pellets revealed the activation energies for charge transport. Thermogravimetric analysis, temperature-dependent X-ray diffraction data, and humidity-dependent measurements on powder pellets revealed the activation energies for charge transport and the role of proton conductivity.

“…In Table 1, some of the analytical characteristics obtained in this work are compared with those previously reported in the literature. [60][61][62][63][64][65][66][67][68] As seen, with a GCE as the basal electrode for the determination of N 2 H 4 , the linear dynamic range, the detection limit and sensitivity of the sensor based on the Co-GE/GCE are superior to previously reported N 2 H 4 sensor. When a gold electrode was used as the basal electrode for N 2 H 4 sensing, a high sensitivity was accompanied by a narrow linear range due to the inherent properties of the basal electrode.…”

A facile, one-pot ultrasonic electrochemical method to synthesize hierarchical cobalt (Co)-nanoflowers on petalage-like graphene (GE) was developed. The hybrid microstructures were successfully evaluated as a new material for highly sensitive determination of hydrazine (N(2)H(4)). Scanning electron microscopic measurements displayed that the synthesized Co-GE exhibited a related hierarchical structure of a petalage-like GE homogeneous distribution as a matrix for the growth of smooth nanosheets-assembled Co nanoflowers. Co-GE was confirmed by energy dispersive X-ray spectrograms. Electrochemical methods were adopted to characterize the sensing properties of Co-GE towards the electrocatalytic oxidation of N(2)H(4) at 0.15 V in 0.1 M pH 7.0 sodium phosphate buffered saline. The sensor displayed a broad linearity of 0.25-370 μM and 370 μM to 2.2 mM with a relatively low detection limit of 0.1 μM (S/N = 3) and a response time of less than 3 s. Furthermore, the sensor showed outstanding sensitivity and reproducibility.
