Co3O4 nanoparticles were synthesized via a simple Co-precipitation reaction between precursors of cobalt and NH3. The effect of different parameters such as concentration of NH3 and precursors of cobalt on the size and photocatalytic activity of the products was investigated. The achieved nanoparticles were characterized by X-ray powder diffraction analysis, field emission scanning electron mic...

A multifunctional Cu(I) coordination polymer constructed from helical chains showed unusual mechanochromic, sensing of nitrobenzene and photocatalytic properties on degradation of organic dyes.

Since groundwaters are a major source of drinking water, their pollution with organic contaminants such as methyl tertiary-butyl ether (MTBE) is a very significant issue. Hence, this research investigated the photocatalytic degradation of MTBE in an aqueous solution of TiO2-ZnO-CoO nanoparticle under UV irradiation. In order to optimize photocatalytic degradation, response surface methodology w...

An efficient photocatalyst consisting of CdS nanoparticle dispersed mesoporous silica-titania was prepared using amphiphilic triblock copolymer P123 as template and silica-titania sol–gel precursors. The CdS nanoparticle was incorporated into silica-titania mesoporous nanosturctures by post impregnation method. The synthesized catalyst has been characterized by FTIR, TEM, SEM, and EDAX analysis...

The nano sized TiO2 and ZnO are the most active photocatalysts.  Methylene blue was used as a reference molecule for the photocatalytic degradation. The TiO2 and ZnO can totally remove methylene blue dye. The effect of various process parameters like initial concentration, contact time, dose of catalyst and pH on the extent of removal of dye by photocatalysis in presence o...

Photocatalytic degradation of pesticides with titanium dioxide (TiO(2)) and other catalysts has shown promise as a potential water remediation method. Titanium-based powders have been used in photocatalytic degradation studies but have limitations. The objective of this study was to determine picloram degradation in water using various UV light sources and low-pressure metal organic chemical va...

A detailed study on visible light photocatalytic degradation of methylene blue (MB) has been investigated in aqueous heterogeneous media containing hexagonal phase molybdenum oxide (h-MoO3) nanocrystals (NCs) which was identified as a new material for visible light driven photocatalysis. A simple and template-free solution based chemical precipitation method was employed to synthesize h-MoO3 NC...

WO3-treated fullerene/TiO2 composites (WO3-fullerene/TiO2) were prepared using a sol-gel method. The composite obtained was characterized by BET surface area measurements, X-ray diffraction, scanning electron microscopy, energy dispersive X-ray analysis, transmission electron microscopy, and UV-vis analysis. A methyl orange (MO) solution under visible light irradiation was used to determine the...
