[ 1 ] - TiO2 Thin Film: Preparation, Characterization, and its Photocatalytic Degradation of Basic Yellow 28 Dye

In this research, the thin films of N-S doped titanium dioxide (TiO2) were successfully prepared by simple sol-gel method in the presence of tetrabutylorthotitanate as a starting reagent. Furthermore, titanium dioxide (TiO2) was functionalized with thiourea. Furthermore, N-S doped titanium dioxides (NSTO) were fixed on glass balls by glass balls fixed-bed reactor system. Besides, the effect of ...

[ 2 ] - Study and Electrochemical Determination of Tyrosine at Graphene Nanosheets Composite Film Modified Glassy Carbon Electrode

A graphene nanosheets (GNS) film coated glassy carbon electrode (GCE) was fabricated for sensitive determination of tyrosine (Tyr). The GNS-based sensor was characterized by scanning electron microscope and electrochemical impedance spectroscopy. The voltammetric techniques were employed to study electro-oxidation of Tyr. The results revealed that the modified electrode showed an electrocatalyt...

[ 6 ] - Photocatalytic degradation of rhodamine B, and phenol red dyes using NiMn2O4 nanoparticles prepared by a new approach

NiMn2O4 nanoparticles have been successfully prepared through sol-gel method. The effects of different factors such as the type of solvent, and amino acid temperature were investigated on the size and morphologies of products. The smallest particle size of NiMn2O4 nanoparticles was found to be 25 nm in diameter. The magnetic properties of the samples were also measured by an alternating gradien...

[ 7 ] - Fabricant and characterization of SrWO4 and novel silver-doped SrWO4 using co-precipitation method: their photocatalytic performances for methyl orange degradation

A simple co-presipitation method has been developed to synthesize SrWO4 and Ag°-SrWO4 micro/nanostructures with different morphologies, including platelet-, star- and flower-like, in the presence of Na(B(C6H5)) as surfactant. The formation of platelet-, star- and flower-like shapes of particulate system was examined by electron microscopy technique. The products were characterized by X-ray diff...

[ 8 ] - Investigation of corrosion protection properties of TiO2-CdO nanocomposite coating prepared by sol-gel method on copper

the Sol–gel nanocomposite coatings have been investigated for copper metal as a potential replacement for the hazardous and banned hexavalent chromate conversion coatings. TiO2–CdO nanocomposite thin films were deposited on copper using the sol–gel method. The sol-gel coatings were prepared using a sol obtained by the hydrolysis and condensation of tetra-o-butyl titanate. They were doped with c...
