A reverse-micelle sol-gel method was chosen for the preparation of Fe-doped TiO2 samples that were employed in photodegradation crystal violet dye under visible light irradiation a batch reactor. The dopant amount varied to assess optimal photocatalyst composition towards target degradation. photocatalysts characterized through multi-technique approach, envisaging XRPD and QPA as obtained by Rietveld refinement, FE-SEM analysis, DR UV-vis spectroscopy, N2 adsorption/desorption isotherms...
This study was focused on the application of white and blue light emitting diodes (LEDs) as sources for photocatalytic degradation organic dyes in liquid phase with visible light. The activity N-doped titanium dioxide, synthesized by direct hydrolysis tetraisopropoxide ammonia, evaluated means a batch photoreactor. bandgap energy dioxide moved range from 3.3 eV to 2.5 eV. responsive photocatalysts showed remarkably effective decolorization process removal total carbon. Methylene also used...
Abstract High energy ball milling (HEBM) was utilized, as an innovative process, to incorporate carbon nanotubes (CNTs) into a polyethylene (PE) matrix avoiding: high temperatures, solvents, ultrasonication, chemical modification of nanotubes. Composites with 1, 2, 3, 5, and 10 wt % were prepared. Films obtained melting the powders in hot press. Morphology physical properties (thermal, mechanical, electrical properties) evaluated. The used processing conditions allowed obtain satisfactory...
Abstract BACKGROUND Heterogeneous photocatalysis for the degradation of non‐biodegradable organic contaminants in wastewater is an alternative to traditional treatment techniques. Since applications developed employ photocatalysts powder form, a main disadvantage remains related recovery from treated wastewater, resulting damage and shorter lifetime recirculation pumps. Structured offer valid solution simplify process; however, they have guarantee light transmission, long‐term stability...
In this paper, the effect of light modulation on photocatalytic ceftriaxone (CEF) degradation in aqueous solution was investigated. The experimental set-up consisted a fixed bed reactor with flat plate geometry and visible LEDs for irradiation. Fe-N-codoped TiO2 photocatalyst immobilized polystyrene (PS) by solvent casting method to achieve structured (Fe-N-TiO2/PS), which loaded photoreactor. Raman UV–Vis diffuse reflectance spectroscopy confirmed presence Fe-N-TiO2 PS surface its uniform...
Metal and metal oxide nanostructured materials have been chemically physically characterized tested concerning methylene blue (MB) photoremoval UV antibacterial activity against Escherichia coli Staphylococcus aureus. In detail, silver nanoparticles commercial BaTiO3 were modified to obtain nanocomposites through sonicated sol-gel TiO2 synthesis the photodeposition of Ag nanoparticles, respectively. The characterization results pristine nanomaterials synthetized photocatalysts revealed...
The empty space in different crystalline and clathrate phases of syndiotactic polystyrene (s-PS) is evaluated by a numerical procedure. It shown that the δ form nanoporous includes two identical cavities per unit cell, whose shape volume are characterized. As consequence clathration, cell enlarged cavity able to include molecules definitely larger than its starting size. Sorption experiments nitrogen at 77 K for s-PS powders forms also presented. These can be interpreted inclusion three...
We present the fabrication of thick and dense carbon nanotube networks in form freestanding films (CNTFs) study their electric resistance as a function temperature, from 4 to 420 K. A nonmetallic behavior with monotonic R(T) temperature coefficient around −7×10−4 K−1 is generally observed. behavioral accordance CNTF conductance measured by solid-state thermistor (ZnNO, Si, or Pt) demonstrated, suggesting possibility using CNTFs small-sized (freely scalable) sensors, besides being confirmed...
FeN -co-doped TiO2 photocatalysts are prepared by sol–gel method using titanium tetraisopropoxide, urea and iron(II) acetylacetonate as precursors of titania, nitrogen iron, respectively. The samples analysed from chemical-physical point view X-ray diffraction (XRD), Raman spectroscopy, UV–Vis diffuse reflectance spectroscopy (UV–Vis DRS), specific surface area measurements scanning electron microscopy (FESEM). DRS spectra evidence that the co-doping with N Fe leads to narrowing band gap...
