Silver oxide, ruthenium oxide nanomaterials and its composites are widely used in a variety of applications. Plasma-mediated synthesis is one the emerging technologies to prepare with desired physicochemical properties. In this study, dielectric barrier discharge (DBD) plasma was synthesize Ag2O Ag2O/RuO2 nanocomposite materials. The prepared materials showed good crystallinity. surface morphology exhibited “garland-like” features, it changed “flower-like” “leaf-like” at different NaOH...
One-dimensional (1D) nanostructured materials have attracted a great deal of interest owing to their potential applications in various industries. Due the limitations and cost associated with conventional low-pressure plasma systems, atmospheric-pressure techniques such as dielectric barrier discharges (DBDs) are investigated an alternative approach for inducing specific chemical reactions. RuO2 nanomaterials widely used supercapacitor electrodes, field-emission devices catalytic...
Marine environment often restrain toxic heavy metals that may enter into the food web via uptake by microalgae and eventually cause severe poisoning problems at higher tropic levels. The effects of Zinc cations upon growth five native microalgal species, Chlorella marina, Isochrysis galbana, Tetraselmis sp., Nannochloropsis Dunaliella salina were evaluated. Growth inhibition cells determined exposing them to different concentrations aqueous solutions zinc metal for 15 days. A major reduction...
Ruthenium oxide nano-catalysts supported on mesoporous γ-Al2O3 have been prepared by co-precipitation method and tested for CO oxidation. The effect of polyethylene glycol (PEG) the properties catalyst was studied. Addition PEG surfactant acted as a stabilizer induced change in morphology ruthenium from spherical nanoparticles to one-dimensional nanorods. Total conversion measured function at 175 °C 200 with 1.0 wt.% loading PEG-stabilized un-stabilized catalysts, respectively. Conversion...
The morphological disorder in multilayer graphene behaves like a semiconductor low temperature.
This research dealt with the preparation and characterization of silver oxide (SLO) nanomaterials (NMs) their composite catalysts (i.e., ruthenium (SLORUO)). The prepared materials were tested for catalytic performance in carbon monoxide (CO) oxidation. Generally, its pure state is not widely used CO oxidation due to stability structural issues. However, usage subsurface oxygen oxygen-induced reconstruction could be effective as an catalyst at a slightly high temperature. low-temperature...
In order to synthesize the zinc-titanium (Zn-Ti) oxide nanocomposites using an atmospheric soft plasma jet, in this study mixtures of Zn and Ti precursors such as zinc nitrate titanium butoxide were first prepared with different molar ratios; mixed then stirred at 700 rpm for two hours plasma, while maintaining a temperature 25 °C. All synthesized Zn-Ti post-heat-treated 600 °C six electrical furnace. The morphology, particle shape size, crystal structure, oxidation state, composition ratio...
Abstract In this study, plasma‐enhanced chemical vapor deposition of cyclohexane thin films was prepared for application towards ethanol and ammonia sensing between the range 100 1,000 ppm. The deposited film exhibited stable, uniform coating smooth surface morphology with minor roughness. thickness coatings 40–46 nm. gas‐sensing behavior against experimental parameters such as thickness, operating temperature, gas concentration investigated. It noted that increasing reduced sensor's...
