Metallic silver (Ag) is known as an efficient electrocatalyst for the conversion of carbon dioxide (CO2) to monoxide (CO) in aqueous or nonaqueous electrolytes. However, polycrystalline electrocatalysts require significant overpotentials order achieve high selectivity toward CO2 reduction, compared side reaction hydrogen evolution. Here we report a high-surface-area Ag nanocoral catalyst, fabricated by oxidation–reduction method presence chloride anions medium, electro-reduction CO with...
Platinum monolayer core–shell nanocatalysts were shown to have excellent catalytic activities and stabilities. Usually, they are fabricated via electrochemical routes. Here, we report a surfactant-free, ethanol-based, wet chemical approach coating Pd nanoparticles with uniform Pt atomic layers, inspired by aerobic alcohol oxidation catalyzed the cores. The as-prepared electrocatalysts also exhibited high electrocatalytic performance toward oxygen reduction reaction.
Proton exchange membrane fuel cells (PEMFCs) have attracted much attention as an alternative source of energy with a number advantages, including high efficiency, sustainability, and environmentally friendly operation. However, the low kinetics oxygen reduction reaction (ORR) restricts performance PEMFCs. Various types catalysts been developed to improve ORR but this problem still needs further investigations improvements. In paper, we propose advanced Os/Pt core–shell based on our previous...
This paper describes the effect of halide anions (X = Cl, Br, I) immobilized on surface nanostructured silver electrocatalysts efficiency and mechanism CO2 reduction to CO in aqueous carbonate solutions. A simple oxidation–reduction cycle Ag foil presence produces high-surface-area catalysts mainly composed metallic with a small amount attached electrode (X–Ag) as demonstrated by XPS, XRD, SEM studies. The activity X–Ag 0.1 M NaHCO3 at pH 6.8 is significantly higher than that or...
The resistance of β-tin decreases by 10% under electromigration because the anisotropic properties material during and consequent rotation grains. diameter grains was measured ex situ angle rotating directly calculated. increased in proportion to time for which current applied. At higher temperature, at effect stronger, an unexpected behavior observed. kinetics atomic movement along a c axes various test conditions is discussed.
The growth of the AlGaSb∕InAs high-electron-mobility transistor (HEMT) epitaxial structure on Si substrate is investigated. Buffer layers consisted UHV/chemical vapor deposited grown Ge∕GeSi and molecular beam epitaxy-grown AlGaSb∕AlSb∕GaAs were used to accommodate strain induced by large lattice mismatch between HEMT substrate. crystalline quality was examined x-ray diffraction, transmission electron microscopy, atomic force microscopy. Finally, very high room-temperature mobility...
Conventional antireflection coating by thin films of quarter-wavelength thickness is limited material selections and these films’ refractive indices. The optimal design non-quarter-wavelength presented in this study. A multilayer thin-film model developed the admittance loci to show that two-layer film SiNx/SiOy at 124/87 nm three layer SiNx/SiNy/SiOz 58/84/83 can achieve average transmittances 94.4% 94.9%, respectively, on polymer, glass, silicon substrates. validated plasma enhanced...
Structures and properties of PtRu electrocatalyts, derived from the aligned RuO2 nanorods (RuO2NR), are investigated using scanning electron microscopy, transmission X-ray diffraction, photoelectron spectroscopy, cyclic voltammetry toward COads methanol oxidation. The catalytic activity oxidation CO tolerance promoted significantly by reducing into Ru metal before decorating with Pt. Reduction RuO2NR was carried out either thermal decomposition at 650 degrees C in vacuum or H2-reduction 130...
An electroless Ru plating bath is prepared by mixing precursor (K2RuCl5·xH2O), oxidizer (NaClO), stabilizer (NaOH), and reducing agent (NaNO2) simultaneously in deionized water at a molar ratio of 1:1:20:10. Instead conventional direct reduction route, the RuCl5 2− experiences an oxidative-reductive sequence to form metallic on activated Si substrate. Spectra from ultraviolet-visible X-ray absorption spectroscopy indicate that oxidized RuO4 initially, followed slight becoming 2−. The...
