In this review, the recent progress in electrochemical sensing of dopamine with various graphene and their nanocomposite materials modified electrodes are presented.
This article presents the effect of different calcination temperatures on structural, morphological and capacitance nickel phosphate (Ni<sub>3</sub>(PO<sub>4</sub>)<sub>2</sub>) as an electrode material for supercapacitor applications.
We investigated different molar concentrations of cobalt precursor intercalated reduced graphene oxide (rGO) as possible electrode materials for supercapacitors.
This work reports on synthesis of zinc oxide/reduced graphene oxide (ZnO/rGO) nanocomposites in the presence diethylenetriamine (DETA) via a facile microwave method. The X-ray diffraction (XRD) patterns correspond to ZnO hexagonal phase wurtzite structure. high-resolution transmission electron microscopy (HRTEM) images revealed that nanorods, with an average length : diameter ratio 10, were successfully deposited rGO sheets. Under irradiation sunlight, showed enhanced...
A facile and fast approach for the synthesis of a nanostructured nickel hydroxide (Ni(OH)2) via sonochemical technique is reported in present study. The X-ray diffraction results confirmed that synthesized Ni(OH)2 was oriented β-phase hexagonal brucite structure. electrode exhibited maximum specific capacitance 1256 F/g at current density 200 mA/g 1 M KOH(aq). electrodes pseudocapacitive behavior due to presence redox reaction. It also long-term cyclic stability 85% after 2000 cycles,...
To overcome the critical limitations of liquid-electrolyte-based dye-sensitized solar cells, quasi-solid-state electrolytes have been explored as a means addressing long-term device stability, albeit with comparatively low ionic conductivities and performances. Although metal oxide additives shown to augment conductivity, their propensity aggregate into large crystalline particles upon high-heat annealing hinders full potential in electrolytes. In this work, sonochemical processing has...
We report on the photocatalytic degradation of methylene blue (MB) solution using commercial ZnO and TiO2 (P25) photocatalysts, in form slurry immobilized glass slides, under ultraviolet (UV) solar irradiations. The average particle sizes P25 were 100 nm 30 nm, respectively. Under both irradiations, activities resulted better performance than photocatalysts. Interestingly, showed capability comparison to irradiation. This result revealed that light provided a good source energy degrade MB...
