CoFe2O4/CdS nanocomposite: Preparation, characterisation, and application in sonocatalytic degradation of organic dye pollutants

Sonocatalytic removal of an organic dye using TiO2/Montmorillonite nanocomposite.

The sonocatalytic performance of the synthesized TiO2/Montmorillonite K10 (TiO2/MMT) nanocomposite was studied in removal of Basic Blue 3 (BB3) from water. The TiO2/MMT nanocomposite was prepared by hydrothermal method. Scanning electron microscope, X-ray diffraction and Fourier transform infrared were used to characterize the synthesized nanocomposite. The average size of TiO2 nanoparticles de...

Sonocatalytic performance of Er3+:YAlO3/TiO2–Fe2O3 in organic dye degradation

In this study, the Er:YAlO3 as up-conversion luminescence agent, which can transfer the visible light part in the sonoluminescence to ultraviolet light, was synthesized by nitrate–citrate acid and sol–gel method. And then the Er:YAlO3/TiO2–Fe2O3 composite as a sonocatalyst was prepared by ultrasonic dispersion and liquids boil method. The prepared Er:YAlO3/TiO2–Fe2O3 composite was characterized...

Photocatalytic Application of Titania Nanoparticles for Degradation of Organic Pollutants

Photocatalytic Degradation of Organic Pollutants in Water

A photocatalyst is defined as a substance which is activated by adsorbing a photon and is capable of accelerating a reaction without being consumed [1]. These substances are invaria‐ bly semiconductors. Semiconducting oxide photocatalysts have been increasingly focused in recent years due to their potential applications in solar energy conversion and environmen‐ tal purification. Semiconductor ...

Degradation and removal of organic pollutants by BaFe2O4 nanostructures, synthesis and characterization

BaFe2O4 nanostructures have been synthesized through a simple sonochemical reduction approach. X-ray diffraction characterization suggested that the product consists of cubic phase pure BaFe2O4. The as-prepared products were also characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). An X-ray energy dispersive spectroscopy (EDX) study further confirmed t...
