“…Additionally, the rGO retained 81% of its specific capacitance after 500 cycles [89]. The deoxygenation of GO using Citrus grandis and Tamarindus indica revealed excellent conductivity (47.33 F g −1 and 65.25 F g −1 , respectively) and high specific capacitance (4090 Sm −1 and 5545 Sm −1 , respectively), making them suitable materials for supercapacitor applications [85]. The rGO that employed aqueous ginger extract refluxed at 90 • C for 12 h demonstrated excellent electrical conductivity, the highest specific capacitance value, and charge-discharge cyclic stability.…”

Graphene, a remarkable material, is ideal for numerous applications due to its thin and lightweight design. The synthesis of high-quality graphene in a cost-effective and environmentally friendly manner continues to be a significant challenge. Chemical reduction is considered the most advantageous method for preparing reduced graphene oxide (rGO). However, this process necessitates the use of toxic and harmful substances, which can have a detrimental effect on the environment and human health. Thus, to accomplish the objective, the green synthesis principle has prompted researchers worldwide to develop a simple method for the green reduction of graphene oxide (GO), which is readily accessible, sustainable, economical, renewable, and environmentally friendly. For example, the use of natural materials such as plants is generally considered safe. Furthermore, plants contain reducing and capping agents. The current review focuses on the discovery and application of rGO synthesis using extracts from different plant parts. The review aims to aid current and future researchers in searching for a novel plant extract that acts as a reductant in the green synthesis of rGO, as well as its potential application in a variety of industries.

“…[9] Plant extracts also prevent aggregation and surface alteration, preventing re-stacking. [39,40] To improve the energy and power densities of electrochemical double-layer capacitors, researchers have invested great effort in studying pseudocapacitive metal oxides. [41] Nickel-based electrodes have been regarded as the most promising materials among the various transition metals because they have a greater theoretical specific capacitance, are inexpensive, ecologically acceptable, and are accessible.…”

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.
