“…Figure 1d shows the deconvoluted spectrum of Co 2p, which exists in four spin‐orbit components and two satellites. The four spin‐orbit components are located at 774.9, 780.1, 790.2, and 795.8 eV and are attributed to Co 2p 3/2 and Co 2p 1/2 , respectively [33] . The binding energy difference of 14.9 eV at strong energy peaks suggests the existence of mixed Co 2+ and Co 3+ ions.…”

Dealing with overcoming the sluggishness of the oxygen evolution reaction (OER), the urea oxidation reaction (UOR) existed. ZnCo2O4, an excellent OER electrocatalyst, its application towards UOR is studied with surface‐grown polydopamine (PDA). ZnCo2O4@PDA is produced over the surface of nickel foam by hydrothermal method followed by self‐polymerization of dopamine hydrochloride. Dopamine hydrochloride was varied in solution mixture to study the optimal growth of PDA necessary to enhance electrochemical activity. Hence, prepared ZnCo2O4@PDA is characterized by X‐ray diffraction, electronic structural, and morphology/microstructure studies for confirmation. With successful confirmation, the developed electrode material is applied towards UOR and ZnCo2O4@ PDA‐1.5, delivering an excellent low overpotential of 80 mV @ 20 mA/cm2 in the electrolyte mixture of 1 M potassium hydroxide + 0.33 M urea. Also, to support excellent UOR activity, other electrochemical properties such as tafel slope, electrochemical surface active sites, and electrochemical impedance spectroscopy are studied. Further, a schematic illustration explaining the UOR mechanism is shown to clearly understand the obtained electrochemical activity. Finally, urea water electrolysis is carried out in a two‐electrode symmetrical cell and compared with water electrolysis. This clearly shows the potential of the developed material for efficient electrochemical hydrogen production.

Green nanotechnology is an emerging field of science that focuses on the production of nanoparticles by living cells through biological pathways. This topic plays an extremely imperative responsibility in various fields, including pharmaceuticals, nuclear energy, fuel and energy, electronics, and bioengineering. Biological processes by green synthesis tools are more suitable to develop nanoparticles ranging from 1 to 100 nm compared to other related methods, owing to their safety, ecofriendliness, non-toxicity, and cost-effectiveness. In particular, the metal nanoparticles are synthesized by top-down and bottom-up approaches through various techniques like physical, chemical, and biological methods. Their characterization is very vital and the confirmation of nanoparticle traits is done by various instrumentation analyses such as UV-Vis spectrophotometry (UV-Vis), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), atomic force microscopy (AFM), annular dark-field imaging (HAADF), and intracranial pressure (ICP). In this review, we provide especially information on green synthesized metal nanoparticles, which are helpful to improve biomedical and environmental applications. In particular, the methods and conditions of plant-based synthesis, characterization techniques, and applications of green silver, gold, iron, selenium, and copper nanoparticles are overviewed.
