This paper deals with an advanced colorimetric method used to determine the catalase mimetic activity of V2O5 nanoparticles by measuring the decrease in potassium permanganate concentration in a mixture containing V2O5 and hydrogen peroxide. The experiments were carried out in batch reactor at room temperature for 3 min at wavelength number of 525 nm. Vanadium pentoxide was synthesized by hydrothermal method (reflux) from ammonium metavanadate (NH4VO3) as a precursor and cetyltrimethylammonium bromide as a surfactant. The annealing of the product was carried out for 2 h, at temperatures of 250, 500 and 750 °C. In order to determine the structure and the chemical nature of the nanoparticles prepared, the characterization was carried out by X-ray diffraction and scanning electron microscopic techniques. Atomic force microscopic and thermal gravimetric investigations have shown the decomposition steps of V2O5 at different temperatures. UV–visible spectroscopic technique and Fourier transform spectrometry were used to further characterize the nanoparticles. Advanced colorimetric method was used to study the catalase mimetic activity of the newly synthesized vanadium pentoxide (V2O5) nanoparticles using hydrogen peroxide (H2O2) as substrate. V2O5 nanoparticles resulted in an increase in the catalase mimetic activity with increasing the annealing temperature of the V2O5 nanoparticles. The maximum activity was found at 500 °C, which subsequently decreased with further increase in the annealing temperature.

“…This method is most frequently used to synthesise stable monodisperse suspensions with the ability to self-assemble. 74,75 The metal precursor is first added to a hot solution in the presence of a surfactant or stabiliser for the synthesis of Cu NMs. Simultaneously, the growth of the Cu NMs occurs at a high temperature, which maintains the nucleation of individual atoms, and the whole process is performed under inert conditions.…”

“…Microorganisms such as algae, [47][48][49][50] fungi, [51][52][53][54][55] yeast, [56][57][58][59] bacteria, [60][61][62][63] viruses, [64] and other natural biological materials are utilized to design "green" spinel ferrite nanoparticles (Figure 7). However plants [65][66][67][68][69][70] has sparked great attention in recent years due to their low cost, renewability, low cytotoxicity, and easy processing [71][72][73] to synthesize ferrite nanoparticles. Phytochemicals present in the plant extracts play a major role in reducing metal salts to metal oxide nanoparticles.…”

Nanotechnology is very important in developing sustainable technologies for the future. Increased demand for metal and metal oxide nanoparticles has led to their large‐scale production using conventional chemical methods with various toxic solvents. These techniques produce poisonous and harsh products that present a biological risk to the environment and have terrible effects on the life of microbes, plants, vertebrates, and invertebrates at different trophic levels. Thus eco‐friendly “green” synthesis methods have become necessary to synthesize nanoparticles using biological entities, such as plants and microorganisms. When compared to other methods, “green” synthesis is safer for human health and the environment. Plants, the main factory for the green synthesis of nanoparticles, have been used extensively for this purpose. This review, focuses on eco‐friendly synthesis to design spinel ferrite nanoparticles, particularly, using extracts from plant products that act not only as precursors but also as reductants and stabilizers during the synthesis process. The outstanding features of these nanoparticles allows for their promising applications in catalysis, lithium‐ion batteries, information storage, magnetic cores, ferrofluids, microwave, and medicine. This important review also highlights noteworthy recent developments related to the green synthesis of plant‐mediated magnetic spinel nanoparticles and their fundamental applications.
