“…The most intense peak at 35.56°belongs to ferrite structure. The diffraction pattern observed for the synthesized CuFe 2 O 4 nanoparticles was supported by previous reports in the literature [22,23]. The average particle size was 15 nm which is calculated using the following Debye-Scherer equation [24] as follows;…”

In the present study, we describe a facile strategy for the easy removal of the heavy metal ion, Pb (II) using biosynthesized copper ferrite (CuFe2O4) Nanoparticles (Nps) prepared via a cost-effective and eco-friendly method using Pimenta dioica leaf extract. The structural characterization was performed using UV-Visible, FT-IR, XRD, XPS, TG, SEM - EDS and TEM techniques. Various characterization techniques showed that the biosynthesized CuFe2O4 nanoparticles have spherical shape with minimum aggregation and possess a size range between 7-16 nm. Batch experiments were carried out to analyze the adsorption efficiency of CuFe2O4 Nps by varying different experimental conditions such as pH, adsorbent dose and initial metal ion concentration. From the Atomic Absorption Spectroscopy (AAS) results, the optimum removal efficiency (99.69 %) occurred at a contact time of 90 min in the solution having pH 6 with 0.06 g of nanoadsorbent. The experimental data were analyzed using adsorption isotherm and fitted with kinetic models. In the present study, we report the the highest removal efficiency of 99.69 % for Pb (II) ions with minimum experimental parameters which is greater than other similar reported studies. The novel CuFe2O4 nanosorbent synthesized in the present study is highly effective in eliminating toxic pollutants. They also possess outstanding recycling characteristics for the effective removal of Pb (II) ions from aqueous media.This cost-effective and ecofriendly strategy could be utilized for addressing the emerging water contamination.

Water splitting has been one of the potential techniques as a clean and renewable energy resource for the fulfillment of world energy demands. One of the major aspects of this procedure is the exploitation of efficient and inexpensive electrocatalysts due to the fact that the water oxidation procedure is accompanied by a delayed reaction. In this research, ZnO-CoFe2O4 nanostructure was successfully synthesized via the green method and green resources from cardamom seeds and ginger peels for oxygen evolution reaction (OER). The modified Glassy carbon electrode (GCE) with ZnO-CoFe2O4 is effective for the electrochemical water oxidation interaction since it has sufficient electrical strength and excellent catalytic performance. The creation of rice-like and small granular structures of ZnO-CoFe2O4 nano-catalysts was confirmed by characterization methods such as XRD, FESEM, EDS and MAP. According to the achieved results, in the electrolysis of water, with in-cell voltage of 1.40 V and 50 mA cm–2 for current density in a 0.1 M KOH electrolyte and OER only has 170 mV overpotentials.
