“…It is further observed that synthetic CoONPs exhibit excellent degradation efficiency towards MX compared to TY. We have made a comparison of reactivity among the degradation efficiency of CoONPs photocatalysts towards different dyes and catalysts (Table 1) [40][41][42][43][44][45] . The present CoONPs shows an excellent efficiency compared to the other CoONPs.…”

“…Until date, few photocatalysts are known for the visible light induced degradation MX and TY [33,35,37] . For example, Adekunle et al [41] , studied the photocatalytic degradation of MX employing Co 3 O 4 nanoparticles in aqueous medium and found ~43.60% degradation efficiency (DE) under solar light irradiation for 40 mins. Recently, Hendekhale et al [44] , have reported the NPs.…”

Considering the impact of organic dyes as industrial effluents on the environment, this research study describes the synthesis, structural and morphological characterization, and visible light induced photo-catalytic studies of cobalt oxide nanoparticles (CoONPs). In order to synthesize the CoONPs, a tetra-nuclear cobalt(III)-Schiff base complex was prepared in crystalline phase and employed to produce CoONPs through thermal decomposition of the synthetic precursor. The morphology of the nanoparticle has been delineated with different spectroscopic and analytic methods. Scanning and transmission electron microscopy (FE-SEM and HR-TEM) analyses estimate the cauliflower structured CoONPs with an average size ~80 nm. The photo-catalytic behavior of CoONPs has been tested against murexide and titan yellow dye in aqueous phase. This CoONPs ensure more than 90% of degradation for murexide while ~60% degradation has been observed for titan yellow (TY) in aqueous phase for a same time interval. MX and TY adopt different structures which bring the variation in rate of photosensitization for the synthetic CoONPs photocatalyst and account on the different photocatalytic efficiency towards the degradation of MX and TY in presence of visible light.

“…72 Furthermore, the CoHCF possesses the light switchable magnetism, whereby a charge transfer induced spin transition between the Co II (high spin)-Fe III to Co III (low spin)-Fe II states alters magnetization. 70 Furthermore, Based on the different characteristic of transition metals, some efforts have been made to synthesize and investigate other MHCFs such, as ZnHCF, 73,74 MnHCF, 11,75 AgHCF 76 and YHCF. 70 Furthermore, Based on the different characteristic of transition metals, some efforts have been made to synthesize and investigate other MHCFs such, as ZnHCF, 73,74 MnHCF, 11,75 AgHCF 76 and YHCF.…”

Electroactive ion exchange materials (EIXMs) with unique electrochemically switched ion exchange function have been extensively applied in various fields including high value-added ion recovery, toxic ion removal, energy storage device and electrochimical ion sensor. In particular, the charge and discharge of EIXMs can be electrochemically controlled by external electric field or by redox agent while the charge balance is compensated via the ion exchange with electrolyte solution. To date, the discovered EIXMs mainly involve inorganic compounds with mixed-valence transition metals, organic conducting polymers and organic-inorganic hybrid materials. Compared with their bulk forms, nanostructured EIXMs have aroused considerable research interest recently owing to their unique properties such as larger surface area, better ion diffusion path and more excellent electron transfer property. In this article, the design principles and synthetic routes for the development of various nanostructured EIXMs and their applications in the fields of selective ion separation, supercapacitors and electrochemical ion sensors are reviewed. In addition, the main challenges and future prospects for the further development of high-performance EIXMs are discussed.

“…Unlike the other Prussian blue analogues [22], zinc hexacyanoferrate (III) (ZnHCF) stands out as a unique exception in that it cannot be deposited easily on surfaces like glassy carbon (GC), Pt and Au, as procedures required for adhesion are too involved in nature [23][24][25][26]. In certain cases, ZnHCF films were obtained by electrochemical cycling of zinc electrodes in solutions containing ferricyanide [24], in which nascent Zn ions are produced during the anodic scan complex with ferricyanide in the solution.…”

This work describes the preparation and characterization of size-controlled zinc hexacyanoferrate (III) nanoparticles (ZnH). They were prepared using different proportions of water/formamide in the complexation reaction of Zn 2+ with [Fe III (CN) 6 ] 3À. The materials were characterized by Fourier Transform Infrared Spectroscopy (FT-IR), Ultraviolet-Visible Spectroscopy (UV-vis), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDX) and Cyclic Voltammetry (CV). The cyclic voltammograms of the modified graphite paste electrode with ZnH-1, ZnH-2, ZnH-3 and ZnH-4 showed a well-defined redox couple with formal potential (E u 0) = 0.94 AE 0.01 V (n=20 mV s À1 ; KCl 1.0 M)) attributed to the redox process [Fe II (CN) 6 ]/[Fe III (CN) 6 ] in the presence of Zn 2+. The dependence of particle size on the detection of sulfite was verified.
