Azo dyes are synthetic organic used in the textile, leather, and paper industries. They pose environmental problems due to their toxic persistent nature. The toxicity is presence of azo groups dye molecule that can break down into aromatic amines, which highly aquatic organisms humans. Various treatment methods have been developed remove from wastewater. Conventional wastewater treatments some drawbacks, such as high operating costs, long processing times, generation sludge, formation...
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 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 work, the synthesis of zinc oxide (ZnO) photocatalyst from thermal decomposition acetate (ZnAc) nanoparticles obtained by supercritical antisolvent (SAS) precipitation was investigated. The optimization calcination conditions SAS ZnAc carried out, studying effect temperature (in range 300–600 °C) on production ZnO nanoparticles. particular, it demonstrated that organic residues in and its particle size, thus specific surface area, strongly affect photocatalytic performances....
The presence of azo dyes in textile effluents is an issue major concern due to their potential impact on the environment and human health. In this study we investigate photocatalytic degradation under visible light Reactive Violet 5 (RV5), dye widely used industry. A preliminary screening different titania-based catalysts was carried out identify best candidate for RV5 removal. selected catalyst then tested a stirred aerated lab-scale reactor illuminated with blue light-emitting diode (LED)...
The beneficial effects on ZnO and TiO2 photocatalytic activity resulting from a suitable combination of doping heterojunctions were proposed investigated by synergistic experimental theoretical study. In detail, the ZnO/N-doped heterojunction was synthesized tested in degradation atrazine under UV visible light. Wide-angle X-ray diffraction (WAXD) analysis reveals presence both crystalline phases heterojunction. UV–vis DRS shows that simultaneous N-doped results slight increase band gap...
Supercritical antisolvent precipitation was used to obtain ZnO (undoped) and Fe-doped photocatalysts at different Fe/Zn molar ratio percentages (0.57, 0.75 0.84 mol%). Wide-angle X-ray diffraction showed the hexagonal wurtzite as main crystalline phase of cauliflower-like nanoparticle aggregations (observed from Field Emission Scanning Electron Microscopy) with a mean diameter 54.5 nm for pure nanoparticles higher (in range 109.1–121.5 nm) nanoparticles. XRF confirmed approximate ratios...
