The hazardous toxicity of dye materials, even in low concentrations, harms ecological
systems. It releases a large number of contaminants into the water, resulting as waste water …

Nanostructured TiO2 possesses unique optical and physical properties as well as exhibiting
quantum confinement effects and has attracted much attention in energy conversion and …

Abstract The WO 3/TiO 2 or MoO 3/TiO 2 composites with different compositions have been
prepared by a facile sol–gel method. The obtained composites were characterized using X …

Nano-sized ZnO catalysts were prepared by a direct precipitation method under the optimal
conditions (cal-cination of precursors at 550? C for 120 min). The as-synthesized ZnO …

Sn doped ZnO nanoparticles was synthesized by a sol-gel approach using different
concentrations of Sn to afford ZnO-Sn (5%), ZnO-Sn (10%), and ZnO-Sn (20%). The ZnO-Sn …

Industrial chemicals like organic dyes are typically utilized in textiles to color things. These
industries discard their effluent into the water without any prior treatment, endangering the …

The photocatalytic degradation of malachite green (MG) dye molecules in aqueous solution
was investigated by using palladium (Pd) modified tungsten trioxide (WO3) under simulated …

The TiO 2-WO 3 catalysts were synthesized using hydrothermal method with different molar
ratios of tungsten (W) precursor. The prepared catalysts were characterized using different …

A series of WO 3–ZnO composites with different WO 3 contents was successfully prepared
via a simple aqueous solution route at low temperature. The products were characterized by …
