Synthesis of Poly(vinyl alcohol)-Aided ZnO/Mn2O3 Nanocomposites for Acid Orange-8 Dye Degradation: Mechanism and Antibacterial Activity

Degradation of Azo Dye Reactive Black 5 and Acid Orange 7 by Fenton-Like Mechanism

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...

Synthesis and evaluation of nanohydrogel film containing polyvinyl alcohol/hyaluronic acid/zinc oxide for wound dressing

Therefore, producing a suitable wound dressing to repair injuries is always one of the challenges of researchers. The present study aims to Synthesize a hydrogel film for wound dressing applications. Methods: In this research, a hydrogel film of polyvinyl alcohol / hyaluronic a...

Enhanced Photocatalytic Activity of Polypyrrole/TiO2 Nanocomposites for Acid Violet Dye Degradation under UV Irradiation

Abstract-In-situ chemical polymerization was used to synthesize PPy/ TiO2 nanocomposite. The nanocomposite was characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, Scanning electron microscopy (SEM) and Energy dispersive X-ray spectroscopy (EDX) to ensure the crystallite size, functional groups and morphology of the polymer nanocomposite. The band gap of th...

Thermal Degradation Behavior of Polyvinyl Alcohol/Starch/Carboxymethyl Cellulose/ Clay Nanocomposites

Polyvinyl alcohol (PVA) / starch (S) /Carboxy methyl cellulose (CMC) / Montmorillonite (MMT) bionanocomposite films were prepared from PVA, MMT, CMC and soluble starch aqueous suspensions by casting method in the presence of a plasticizer that contained glycerol. The kinetics of thermal degradation of PVA/S/CMC/MMT blends was investigated by thermogravimetry (TGA) and derivative thermogravimetr...
