An eco-friendly route for green synthesis of ZnO-CoFe2O4 nanoparticles from cardamom and ginger extract as an efficient electrochemical catalyst for water oxidation

Abstract

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.

“…According to these researchers, nano-biomaterials are essential for optimizing some medical solutions.Nanoparticles play a significant role in protecting the environment. In a study by Kamyab et al [5] , the use of green resources from cardamom seeds and ginger peels was used to synthesize the ZnO-CoFe2O4 nanostructure by the oxygen evolution reaction (OER), which is environmentally friendly and serves as an effective electrochemical catalyst for the oxidation of water. Another study by Krishnan and Rajendran [6] demonstrated that hydrophilically modified mesoporous PS-MWCNT composites have rapid adsorption and desorption kinetics of xylene isomers, which can effectively remove toxic substances from the environment.…”
