The advancement of supercapacitor technology is impeded by a dearth of advanced electrode materials that can augment energy storage capabilities. In this-work, we propose a novel, sustainable methodology for synthesizing tin oxide nanoparticles (SnO2-PJ NPs) utilizing Prosopis juliflora aqueous leaf extract as a stabilizing and reducing agent for the first time. These nanoparticles were evaluated in comparison to those synthesized via traditional chemical methods (SnO2-pure NPs). The samples were analyzed using an array of techniques including UV, FTIR, EDX, SEM, PL, XRD and XPS. The results indicated that the SnO2-PJ NPs exhibited superior performance as supercapacitor electrodes in both three-electrode and two-electrode system configurations. The symmetric supercapacitor device SnO2-PJ NPs displayed a high specific capacitance (98 F g−1 at 1 A g−1) and energy density (31 Wh kg−1 at 0.35 kW kg−1) in an acidic electrolyte of 1 M H2SO4. Additionally, the SnO2-PJ NPs demonstrated exceptional cycling stability, maintaining 100% of their specific capacitance after 10,000 cycles. In conclusion, the SnO2-PJ NPs exhibit tremendous potential as a next-generation energy storage material, owing to their high-power density, high-energy density, and outstanding capacity. Additionally, antibacterial and antifungal activity of synthesized SnO2 NPs is studied. The bio-synthesized SnO2 PJ NPs possesses highest antibacterial activity against two Gram-positive bacteria Staphylococcus aureus (17.0 ± 0.08 mm) and Bacillus subtilis (17.5 ± 0.74 mm) as well as one Gram-negative bacteria Escherichia coli (15.0 ± 0.06 mm) at 200 μl. Furthermore, the bio-synthesized SnO2 PJ NPs possesses highest antifungal activity against Aspergillus niger (10.0 ± 0.11 mm) and Aspergillus flavus (08.0 ± 0.12 mm) at 200 μl. The present work demonstrated an eco-friendly preparation of SnO2 NPs with high-performance supercapacitor electrode, good antibacterial and antifungal properties.

The green synthesis of metal oxide nanoparticles is presented as an excellent sustainable alternative for achieving nanostructures, with potential applications. This research provides important information regarding the influence of the type of solvent used in extracting organic reducing agents from E. globulus on the FeO NPs green synthesis protocol. A broad approach to characterization is presented, where UV-vis spectrophotometry suggests the presence of this type of nanoparticulate material. Likewise, the reduction mechanism was evaluated by FT-IR and the magnetic properties were evaluated by PPSM. In addition, characterizations were linked via elemental analysis (EDX), crystallographic characterization (XRD), electron microscopy (SEM/STEM), and Z potential to evaluate colloidal stability. The results show the influence of the type of solvent used for the extraction of organic reducing agents from E. globulus, and the effect on the synthesis of FeO NPs. In addition, the nanostructure material obtained showed excellent efficiency in the remediation of agricultural soil, eliminating metals such as Cr-VI, Cd, and, to a lesser extent, Pb.

“…The core interest of researchers is to understand the effects of dimensions, shapes and sizes of nanostructured materials on their properties. Oxide materials are generally in the spotlight on account of their prospective use in data storage and photonic devices [2][3][4][5]. Among the oxide materials, SnO 2 got a great deal of attention due to its high charge carrier concentration, good transparency, non-stoichiometric nature as well as chemical and thermal stability [6].…”

In this research, pure SnO2 and Ni-doped SnO2 (Ni:SnO2) nanocomposite films were produced by chemical bath deposition method and the latter were coated with multi-walled carbon nanotubes (Ni:SnO2/MWCNTs) or graphene nanoplatelets (Ni:SnO2/GNPs) by spin coating. All samples have tetragonal rutile SnO2 structure with the presence of carbon (002) peak in MWCNTs- or GNPs-coated films. Crystallite size of SnO2 films decreased remarkably with Ni doping followed by a slight decrease with MWCNTs coating and slight increase with GNPs coating. Scanning electron microscope images manifested a dispersed agglomerative nature of SnO2 nanoparticles which reduced especially with MWCNTs coating due to the porous surface provided by carbon nanotubes. From the photoluminescence measurements, oxygen defects-related peaks were spotted in the SnO2-based structures with different luminescence intensities. The most significant decrease in resistance was observed with the addition of GNPs into Ni-doped SnO2 nanocomposites compared to the other produced films mainly due to the synergetic effect that promotes excellent charge transfer between surfaces of Ni:SnO2 and graphene nanosheet. The huge increase in conductivity of GNPs-coated films led to a huge increase in dielectric losses and this followed by a drop down of dielectric constant of the GNPs-coated films.
