Preparation of high-performance supercapacitor electrode with nanocomposite of CuO/NCNO flower-like

Scientific Reports, Год журнала: 2023, Номер 13(1)

Опубликована: Сен. 27, 2023

Due to the importance of energy storage systems based on supercapacitors, various studies have been conducted. In this research CuO, NCNO and flower like CuO/NCNO studied as a novel materials in field. The resulte showed that synthesized CuO nanostructutes morphology which by FE-SEM analisis. Further, XRD pattern confirmed crystalline properties nanocomposite, Raman verified functional groups vibrations components nanocomposite. two-electrode system at current density 4 A/g, capacitance, power density, were 450 F/g, 3200 W/kg, 98 Wh/kg, respectively. charge transfer resistances NCNO/CuO electrodes obtained 8 2 Ω respectively, show conductivity supercapacitive nanocomposite are better than pure components. Also, stability low resistance other advantages two-symmetrical electrode investigation. investigation after 3000 consecutive cycles, only 4% initial capacitance decreased.

One of the most important edible colours is used in various industries Sunset Yellow, which essential to measure according its consumption. Therefore, a new electrochemical sensor prepared food color additives this work. In study, CuNiFe 2 O 4 nanospheres prepare potent modifier for carbon paste electrode (CPE). Due environmental toxicity additives, sensitive, fast and, low-cost determination workplace environments great interest. So, modified CPE was applied as sensitivity analysis approach Yellow present Brilliant Blue and Tartarzin plasma samples. Cyclic voltammetry (CV) differential pulse (DPV) were techniques optimize measurement Yellow. The calibration curve showed linear range from 0.5 150 μ M with detection limit 0.15 Simultaneous three colors, Tartrazine, done on CPE/CuNiFe surface simultaneous received limits are 1.60 M. shows an outstanding ability sunset Sunich syrup jelly real

Noble Metals Functionalized on Graphene Oxide Obtained by Different Methods—New Catalytic Materials

Nanomaterials, Год журнала: 2023, Номер 13(4), С. 783 - 783

Опубликована: Фев. 20, 2023

In recent years, research has focused on developing materials exhibiting outstanding mechanical, electrical, thermal, catalytic, magnetic and optical properties such as graphene/polymer, graphene/metal nanoparticles graphene/ceramic nanocomposites. Two-dimensional sp2 hybridized graphene become a material of choice in due to the excellent it displays electrically, thermally, optically mechanically. Noble nanomaterials also present special physical chemical and, therefore, they provide model building blocks modifying nanoscale structures for various applications, ranging from nanomedicine catalysis optics. The introduction noble metal (NPs) (Au, Ag Pd) into chemically derived is important opening new avenues both different fields where can hybrid with exceptional performance synergistical result specific each materials. This review presents synthetic procedures preparing Pt, Ag, Pd Au NP/graphene oxide (GO) reduced (rGO) composites.
