“…It has been determined that the particle sizes of CoFe 2 O 4 and NiFe 2 O 4 nanoparticles are very small compared to those in the literature [54] . One of the most commonly used techniques to analyze the surface morphology and size of nanoparticles is SEM analysis [55] . SEM analysis of CoFe 2 O 4 and NiFe 2 O 4 nanoparticles was performed, and the images are given in Figure 3.…”

In this report, for the first time, we have applied green synthesized NiFe2O4 and CoFe2O4 nanoparticles as electrode materials for supercapacitors (SCs). Bean pods extracts were used for the green synthesis of NiFe2O4 and CoFe2O4 nanoparticles. The structure and morphology of the samples were characterized by fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), energy dispersive X‐ray (EDX), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). From XRD analysis, it was determined that NiFe2O4 and CoFe2O4 nanoparticles had a crystalline structure. EDX analysis confirms the presence of carbon and the stoichiometries of NiFe2O4 and CoFe2O4. In TEM analyses, it was determined that the sizes of nanoparticles varied in the range of 5–20 nm. The FTIR spectra supported the presence of Fe−O, Ni−O, and Co−O bonds. Electrochemical measurements of active materials were performed using cyclic voltammetry, galvanostatic charge‐discharge, and electrochemical impedance spectroscopy techniques in a 1 M H2SO4 solution. It was determined that the specific capacitance value of NiFe2O4 (129 F/g) was higher than that of CoFe2O4 (106 F/g). The cyclic stability of CoFe2O4 and NiFe2O4 was found to be 59 and 106 % retention at the end of 10000 cycles, respectively. The specific capacitance value and very good cyclic stability of NiFe2O4 showed that it is a good active substance that can be used in supercapacitor applications.

The study investigates the potential of Rhizoclonium hieroglyphicum as a novel source for synthesizing nickel oxide nanoparticles (RH‐NiONPs) and evaluates its biological applications. Phytochemicals in the algal extract serve as capping, reducing and stabilizing agent for nickel oxide nanoparticles. The process variables were optimized using BBD based RSM to obtain maximum RH‐NiONPs. Characterization of RH‐NiONPs using UV–Vis and FT‐IR spectroscopy reveals the plasmon resonance peak at 340 nm and the functional groups responsible for reduction and stabilization. XRD confirmed the crystalline nature while the stability and size of the RH‐NiONPs were determined by DLS and zeta potential. Toxicity assessments demonstrated the effect of RH‐NiONPs against Vigna radiata, Allium cepa and Artemia salina was low. RH‐NiONPs revealed significant zone of inhibition against the selected bacteria and fungi. The results of larvicidal activity showed that RH‐NiONPs are toxic to 4th instar larvae of Daphnis nerii. Also, RH‐NiONPs efficiently decolorized Reactive Violet 13 (92%) under sunlight irradiation and the experimental data well fits to Langmuir isotherm along with pseudo second order kinetic model. The thermodynamic studies enunciate the exothermic and non‐spontaneous photocatalytic decolorization of reactive violet 13. Thus, the current study assesses the eco‐friendly and cost‐effective nature of RH‐NiONPs along with its biological applications.
