“…44,45 This oxidation reactions could potentially produce compounds such as glyceraldehyde and dihydroxyacetone (simultaneous and/or subsequent), which by further oxidation can be converted to some oxidized products as glyceric, tartronic, formic, glycolic and oxalic acid. 44,46 The presence of dihydrate zinc oxalate at the end of stage 2 indicates the occurrence of this process. The oxalate salt observed would result from the dissolution reaction of the zinc ferrite by the oxalic acid formed in situ.…”

Coprecipitation is one of the most practical methods used to synthesize ferrite nanoparticles. Fine characteristics of these materials can be improved by means of a series of modifications in the synthesis method. In this paper we present a study of influence of glycerol as structure directing and stabilizing agent in the synthesis of zinc ferrite nanoparticle, exploring its chelating capacity and oxidation. The studied materials include two series of zinc ferrite samples and its precursors obtained with or without glycerol throughout different stages during the synthesis process. The structural and morphological characteristics were evaluated by means of different techniques such as X-ray diffraction, Fourier transformed infrared spectroscopy, scanning and transmission electron microscopy and thermal analysis. The oxidation of glycerol was determined by high-performance liquid chromatograph. The obtained results demonstrate that zinc ferrite crystals synthesized in the presence of glycerol are initially bigger than those synthesized in absence of it, but according to the oxidation process they tend to decrease giving rise to intermediate phases. Interestingly, these samples grow back during more advanced stages and become structurally better organized, compared to the series of samples produced in absence of glycerol. These results indicate that glycerol is capable to modify the synthesis route of zinc ferrite nanoparticles via coprecipitation, acting directly over the size and morphology of the crystals.

“…Their low cost and abundance in nature make TMO a significant choice for researchers as electrode material for supercapacitors and electrocatalysts for the water-splitting process [21][22][23]. Nanomaterials can be synthesized through various routes including physical, chemical, and biological routes [24][25][26]. However, biogenic synthesis complies organic framework of biological entities as stabilizing and reducing agents, making it environmentally benign and inexpensive route for nanoparticle synthesis, hence favorable compared to other routes [27,28].…”

BackgroundResearchers are keen to reduce the over potential value through fabrication of electrocatalyst consisted of environmentally benign and inexpensive material. Supercapacitors on the other hand have gained immense attention in recent years as an energy storage device due to the high power density potential of these devices as compared to conventional batteries based storage system.AimThe research aims to synthesize nanoscale transition metal oxides (TMO) through green route. TMO based nanomaterials have vast role in energy related applications.Materials & methodsIn this study, organic compounds of A. Viridis were used as reducing and stabilizing agents in the synthesis of binary nanocomposite Sb2O3–ZrO2. The synthesized nanocomposite was characterized using x‐ray diffraction, Fourier transform infrared spectroscopy, ultraviolet–visible spectroscopy, field emission scanning electron microscopy and energy dispersive spectroscopy. The electrode material was analyzed for supercapacitor potential using cyclic voltammetry and galvanostatic charge discharge techniques. HER and OER studies were also conducted using electrochemical impedance spectroscopy and linear sweep voltammetry. The synthesized material was also tested for stability.Results & discussionThe crystal size was 15.9 nm. Optical band gap of 2.55 eV was obtained through Tauc plot. The capacitance value of 339.8 F/g at 2 mV/s and the specific capacitance of 100.6 F/g was obtained at 1 A/g. The overpotential value of 201 mV and Tafel value of 121 mV/dec was recorded for the HER, whereas the lower Tafel value of 106 mV/dec and over potential value of 383 mV was determined for OER. Electrode showed promising stability up to various cycles in case of both applications.ConclusionThe obtained results revealed the promising performance with excellent stability of fabricated electrode for super capacitor as well as water splitting studies.

“…Due to Jahn-Teller distortion, the structural phase transition (SPT) was observed in case of copper ferrites [8]. In the literature, the copper ferrites were prepared using the mechanochemical reactions, co-precipitation, sol-gel auto-combustion, and hydrothermal methods were used to prepare the copper ferrites [9]. Previous scientists clearly indicated the effect of pH on magnetic behavior of nano copper ferrites [10].…”

The zinc copper ferrite nanoparticles were synthesized via hydrothermal method. Further, the X-ray diffraction patterns confirmed the formation of cubic spinel structure. The microstructure was analyzed using the FESEM and TEM study. The results revealed that the symmetrical and asymmetrical nanospheres were found in the surface morphology. The dielectric studies indicated that the behavior of dielectric constant and dielectric loss as a function of frequency and composition. In addition, the Maxwell-Wagner interfacial polarization was observed. Similarly, the ac-electrical conductivity behavior was well understood. The M-H loops indicated the ferromagnetic behavior of ZnCu ferrite samples.
