TiO2/ZnS/CdS Nanocomposite for Hydrogen Evolution and Orange II Dye Degradation

Synthesis, characterization and degradation activity of Methyl orange Azo dye using synthesized CuO/α-Fe2O3 nanocomposite

This study investigated the photo-degradation of methyl orange (MO) as a type of azo dye using a CuO/α-Fe2O3 nanocomposite. A CuO/α-Fe2O3 powder with a crystalline size in the range of 27-49 nm was successfully prepared using simple co-precipitation along with a sonication method. The characterization of the synthesized sample was done via XRD, FE-SEM, EDS, FTIR and DRS analyses. The Tauc equat...

Azo-dye Orange II degradation by Fenton’s reaction using Fe/ZSM-5 zeolite as catalyst

This work deals with the non-biodegradable azo-dye Orange II degradation using the heterogeneous Fenton-like reaction using Fe/ZSM-5 zeolite as catalyst. The influence of some relevant parameters was studied, namely pH and temperature in the ranges 3.0 – 8.5 and 30 – 53 oC, respectively. Decolorization degree, TOC removal and leaching were evaluated along time in the experiments done. It was fo...

Microwave-assisted Synthesis of MgFe2O4-ZnO Nanocomposite and Its Photo-catalyst Investigation in Methyl Orange Degradation

In this work firstly MgFe2O4 nanoparticles were synthesized via a microwave-assisted method. The product was calcinated at 900 ºC for 2h. At the second step zinc oxide shell was synthesized on the ferrite under ultrasonic waves. Properties of the product were examined by X-ray diffraction pattern (XRD), scanning electron microscope (SEM) and Fourier transform infrared (FT-IR) spectroscopy. Vibr...
