A flower-like TiO2-based composite (denoted as Zn-Ti-6) was prepared using a zinc oxide template for adsorption–photocatalytic degradation of high-chroma methylene blue. The reaction took place in an alkaline environment following hydrochloric acid treatment to remove the and form composite. Sodium hydroxide played both roles morphology-directing agent reactive etchant. possible mechanism forma...

In this paper, CuO-ZnO nanocomposite was synthesized and its photocatalytic dye degradation ability from colored wastewater was studied. Basic Red 18 (BR18) and Basic Violet 16 (BV16) were used as model dyes. The characteristics of CuO-ZnO of were investigated using Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscope (SEM) and X-ray diffraction (XRD). Photocatalytic dy...

The present manuscript describes the transformation and mineralization of methadone (MET) in aqueous solutions (demineralized water (DW) and synthetic municipal wastewater effluent (SWeff)) by natural solar irradiation and two solar photocatalytic processes: heterogeneous photocatalysis with titanium dioxide (TiO2) and homogeneous photocatalysis by photo-Fenton. Direct solar irradiation resulte...

In this study, the effectiveness of photocatalytic oxidation (PO) and wet oxidation (WO) processes as a pre-treatment step on improvement of biodegradability and colour removal of mixture of raw domestic and pre-treated industrial wastewaters, have been evaluated. More oxygen was obtained by H2O2 (as an oxidant in WO and PO processes) than stoichiometric demand. PO of the wastewater was carried...

Photocatalytic wastewater treatment technology has been proposed for more than 30 years, but it is still seldom used in industry. The lack of research on high-performance and cost-effective photocatalytic reactors (PWTRs) may be one the major reasons limiting industrial application technology. To accelerate realization application, this review emphasizes importance increased PWTRs. In review, w...

Abstract Ciprofloxacin (CIP) belongs to the fluoroquinolone antibiotic family. It is mostly used for treatment of bacterial infections and highly recalcitrant naturally decompose. The nanocomposite was successfully constructed by zinc ferrite nanoparticle anchored onto graphitic carbon nitride nanosheet (ZFNP–CNNS). structural, morphological, optical properties ZFNP–CNNS were investigated. More...

Colloidal synthesis of photocatalysts with potential to overcome the drawback low photocatalytic efficiency brought by charge recombination and narrow photo-response has been a challenge. Herein, general facile colloidal approach synthesize orthorhombic phase Bi2S3 particles rod flower-like morphology is reported. We elucidate formation growth process mechanisms these synthesized nanocrystals i...

This study aimed to investigate the performance of composite photocatalytic membranes fabricated by incorporating multiple nanoparticles (TiO2, carbon nanotubes, BiVO4) into polyvinylidene fluoride membrane material for real dairy wastewater treatment. The exhibited superior antifouling behavior, lower filtration resistance, better flux, and higher flux recovery ratio than pristine membrane. Sa...
