An "infinite recycling" method for enhancing the durable applications of a ZnS nano-photocatalyst is shown. Based on the finding of thermodynamic stable nanophase of ZnS, we designed a strategy in which the deactivated ZnS nano-photocatalyst could be recovered into its original state. This ZnS photocatalyst can be used repeatedly without being released into environment as nano-waste. The strate...

in this research fe-tio2 nanocomposites with different molar ratios of fe/ti were prepared as nano-photocatalyst using a modified sol-gel process at ambient temperature. crystallographic properties of nanocomposites were characterized by x-ray diffraction (xrd). surface morphology and mean particle size of nanocomposites were specified by field emission scanning electron microscopy (fesem) and ...

Magnetically separable photocatalyst beads containing nano-sized iron oxide in alginate polymer were prepared. This magnetic photocatalyst beads are used in slurry-type reactors. The magnetism of the catalyst arises from the nanostructured particles gamma-Fe(2)O(3), by which the catalyst can be easily recovered by the application of an external magnetic field. These synthesized beads are sunlig...

BACKGROUND Mono aromatic hydrocarbons (BTEX) are a group of hazardous pollutants which originate from sources such as refineries, gas, and oil extraction fields, petrochemicals and paint and glue industries.Conventional methods, including incineration, condensation, adsorption and absorption have been used for removal of VOCs. None of these methods is economical for removal of pollutants of pol...

in this study, the photocatalytic degradation of methyl orange and congo red dye was investigated inaqueous solution using c,n,s-tridoped sno2 nanoparticles as a nano photocatalyst. the degradationwas carried out under different conditions including the photocatalyst amount, initial concentrationand ph of the solution. the results indicated that the degradation of methyl orange and congo redwas...

In this article, a novel BiVO4@fibers composite photocatalyst was prepared by a process that monoclinic scheelite BiVO4 nano/micro particles were in situ formated onto fiber materials. The structure, morphology and photophysical properties of the composite materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-Vis diffuse reflectance spectroscopy, re...

This review provides a background, fundamental and advanced application of titania nanoparticles (TiO2) on the disinfection and killing of cancer cell through photocatalytic chemistry. It starts with the characteristic properties focused on the surface, light sensitivity, crystallinity and toxicology of TiO2 as a photocatalyst. Consequently, outline and design of photocatalytic reactor has been...

Urchin-like micro/nano heterostructure Au@CdS/WO3 was synthesized by using a facile photodeposition method with no need for an additional stabilizer, which can be used as an efficient all-solid Z-scheme visible-light photocatalyst for H2 generation with a high H2 evolution rate.

Plasmonic photocatalytic nanostructures have been fabricated under mild conditions (room temperature aqueous solution) using genetically engineered bacteriophage P22 virus-like particles (VLP) as a nano-platform. The photodegradation of methylene blue by CdS photocatalyst confined inside VLP can be significantly enhanced by the controlled deposition of gold nanoparticles on the outer shell of V...
