A high-performance electrochemical sensor for methyl parathion (MP) detection was developed using silver nanoparticles (AgNPs) integrated with graphene oxide/ionic liquid (GO/IL) on a screen-printed electrode (AgNPs@GO/IL@SPCE) enhanced sensitivity and stability.
WO3 thin films were prepared by RF sputtering metallic tungsten onto glass substrates, followed thermal oxidation through annealing in air. This technique is straightforward, cost-efficient, and time-effective, achieving high deposition rates of 16 nm/min on average at 200 W magnetron power for the highly homogeneous W-metallic films. SEM/EDX analysis showed that after 450?C air, sputtered 269 nm thick with a round grain morphology (~30 nm) turned into 420 nearly stoichiometric transparent...
The development of carbonaceous materials such as biochar has triggered a hot spot in application. In this study, new type char carbon was developed from raw cigarette filter rods (CFRs) via carbonization process under moderate conditions (T = 550 °C; tres 1 h) (CFR carbon). produced characterized by ATR-FTIR (Attenuated total reflectance—Fourier-transform infrared) spectroscopy, XRD (X-ray diffraction) analysis, GC-MS (Gas Chromatography–Mass Spectrometry), FESEM-EDS (Field-Emission...
PtAu nanoparticles spontaneously deposited on graphene support, PtAu/rGO, have shown remarkably high catalytic activity for hydrogen evolution reaction (HER) in sulfuric acid solution. SEM images of the PtAu/rGO electrode surface showed that Pt are non-uniform size occupy both edges previously uniform Au and support. XPS analysis atomic percentages were 0.6% 0.3%, respectively. The percentage alone prepared Au/rGO was 0.7%. Outstanding HER achieved electrode, showing initial potential close...
Catalytic materials are the greatest challenge for commercial application of water electrolysis (WEs) and fuel cells (FCs) as clean energy technologies. There is a need to find an alternative expensive unavailable platinum group metal (PGM) catalysts. This study aimed reduce cost PGM by replacing Ru with RuO2 lowering amount adding abundant multifunctional ZnO. A ZnO@RuO2 composite in 10:1 molar ratio was synthesized microwave processing precipitate green, low-cost, fast method, then...
This study proposes a simple and controlled method for producing TiO2 with phase junction, oxygen vacancies, Ti3+ by combining picosecond pulsed laser irradiation electrochemical anodization. Ti mesh was pretreated irradiating technique using an Nd:YAG (1064 nm) at two fluencies, 15 J/cm2 30 J/cm2. The samples were then subjected to anodization form nanotube arrays on the previously laser-treated surface. will investigate possibility of forming pre-laser-treated substrate determine their...
Eco-friendly and rapid microwave processing of a precipitate was used to produce Fe-doped zinc oxide (Zn1-xFexO, x = 0, 0.05, 0.1, 0.15 0.20; ZnO:Fe) nanoparticles, which were tested as catalysts toward the oxygen reduction reaction (ORR) evolution (OER) in moderately alkaline solution. The phase composition, crystal structure, morphology, textural properties, surface chemistry, optical properties band structure examined comprehend influence Zn2+ partial substitution with Fe3+ on catalytic...
In order to study the effect of Fe cation substitution on local structure, defect formation, and hyperfine interactions in ZnO, Mössbauer spectroscopy measurements microwave processed Zn1−xFexO (x=0.05, 0.10, 0.15, 0.20) nanoparticles, together with ab initio calculations, were performed. Complementary information distribution particle size morphology, as well magnetic properties, obtained by X-ray diffraction, transmission electron microscopy, squid-magnetometry. The selected model for...
In this paper, microwave processing of nanostructured ZnO powder as well preparation ZnO/PEO composite were described. As a fast method which introduces large amount energy in the reaction system, role was to modify crystal structure, while PEO additionally sensitivize surface particles; both approaches used aim improve optical properties zinc oxide comparison with bulk one. The synthesized powders characterized by X-ray diffraction (XRD), Raman spectroscopy, field emission scanning electron...
Water pollution is a significant issue nowadays. Among the many different technologies for water purification, photocatalysis very promising and environment-friendly approach. In this study, photocatalytic activity of Sr0.9La0.1TiO3 (SLTO) Sr0.25Ca0.25Na0.25Pr0.25TiO3 (SCNPTO) nano-sized powders were evaluated by degradation pindolol in water. Pindolol almost entirely insoluble due to its lipophilic properties. The synthesis SCNPTO was performed using reverse co-precipitation method nitrate...
