Gold/Palladium nanoparticles were fabricated by inert-gas condensation on a sputtering reactor. With this method, controlling both the atmosphere chamber and magnetron power, it was possible to produce with high degree of monodispersity in size. The structure size Au/Pd determined mass spectroscopy, confirmed atomic force microscopy electron transmission measurements. chemical composition analyzed X-ray microanalysis. From these measurements we that technique are able particles 1, 3, 5 nm...
Abstract Nanometer size-selected Cu clusters in the size range of 1–5 nm have been produced by a plasma-gas-condensation-type cluster deposition apparatus, which combines grow-discharge sputtering with an inert gas condensation technique. With this method, controlling experimental conditions, it was possible to produce nanoparticles strict control size. The structure and were determined mass spectroscopy confirmed atomic force microscopy (AFM) scanning electron transmission (STEM)...
Humic acid coated magnetic iron oxide nanoparticles (HA-MNPs) were synthesized, characterized, and studied for the removal of toxic inorganic arsenic species from aqueous media. The adsorption As(III) As(V) followed pseudo-second-order kinetics, observed data accurately modeled employing Freundlich isotherm. Application Weber Morris intraparticle diffusion model to kinetic suggests that occurs in three distinct stages, fast, intermediate, slow steps. We propose initial stage is governed by...
The photocatalytic activities of reduced titanium dioxide (TiO2) materials have been investigated by measuring their ability to produce hydroxyl radicals under UV and visible light irradiation. Degussa P25 TiO2 was doped with nitrogen (N), fluorine (F), and/or phosphorus (P) then subjected surface modification employing a thermo-physicochemical process in the presence reducing agent sodium borohydride (NaBH4). were characterized number X-ray, spectroscopic imaging methods. Surface doping...
Abstract In this study, (1 − x) BFO-xCFO (CFO, x = 0.00, 0.05, 0.10 and 0.30) ceramics were synthesized by a solid-state reaction method; their compositions driven structural, microstructural, vibrational, electrical, magnetic properties; enhanced magneto capacitance (MC) effect have also been carried out. Reitveld refinement studies of X-ray diffraction data shows composition-driven structural phase transformation from rhombohedral ( R3c ) to tetragonal P4mm ). Two phonon scattering Raman...
The electrocatalytic reduction of nitric oxide and nitrogen dioxide (NOx) remains a significant challenge due to the need for stable, efficient, cost-effective materials. This study presents novel support system NOx in alkaline media, composed ZrO2-WO3-C (ZWC), synthesized via coprecipitation. Platinum nanoparticles (10 wt.%) were loaded onto ZWC Vulcan carbon support, using similar methods comparison. Comprehensive physicochemical electrochemical analyses (N2 physisorption, XRD, XPS, SEM,...
In this work, we report the fabrication of CuI@g-C3N4/MoS2 thin films by thermal evaporation Cu and their conversion into hybrid a simple wet chemical method. Compared to pure CuI, shows enhanced absorption near UV region, which improves its DC photoconductivity. The conductivity is addition g-C3N4/MoS2, distributed on surface CuI film. band gap red-shifts upon adding g-C3N4/MoS2. We evaluate material’s potential application as photodetector in photocatalysis evaluating photoelectrochemical...
Despite the recent synthesis and identification of a diverse set new nanophotocatalysts that has exploded recently, titanium dioxide (TiO2) remains among most promising photocatalysts because it is inexpensive, non-corrosive, environmentally friendly, stable under wide range conditions. TiO2 shown excellent promise for solar cell applications remediation chemical pollutants toxins. Over past few decades, there been tremendous development variety industrial (i.e. water purification reuse,...
