Investigations of adsorption and photoluminescence properties of encapsulated Al-ZnO nanostructures: Synthesis, morphology and dye degradation studies.

This study focuses on the solution combustion approach to examine the nanostructures of undoped and doped ZnO with different concentrations of Al (0.1 % and 0.2 %).

Encapsulated Co-ZnO nanospheres as degradation tool for organic pollutants: Synthesis, morphology, adsorption and photo luminescent investigations.

Zinc oxide (ZnO) nanostructures, both undoped and Co-doped, were synthesized through the solution combustion process. The diffraction patterns from powder XRD revealed that the materials were crystalline. The morphology of the spherically formed nanoparticles was visualized in SEM micrographs.

Adsorptive removal of Rhodamine B dye from aqueous solution by using graphene-based nickel nanocomposite.

In this work, reduced graphene oxide-nickel (RGO-Ni) nanocomposite is synthesized. X-ray diffraction (XRD), scanning electron microscopy (SEM) and SEM-EDS (Energy Dispersive X-Ray Spectroscopy) are used to study the crystalline nature, morphology and elemental composition of the RGO-Ni nanocomposite, respectively. As synthesized RGO-Ni nanocomposite is used to develop selective adsorptive removal of Rhodamine B (RhB) dye from the aqueous solution.

Nano-catalytic behavior of highly efficient and regenerable mussel-inspired FeO@CFR@GO and FeO@CFR@TiO magnetic nanospheres in the reduction of Evans blue dye.

FeO@catechol formaldehyde resin coated @Graphene Oxide nanocomposite (FeO@CFR@GO) and FeO@catechol formaldehyde resin coated @TiO (FeO@CFR@TiO) nanocomposite were fabricated by hydrothermal method. Particularly, catechol bunches on the highest layer of nanospheres to play a mussel-inspired chemistry to assist combined with graphene oxide (GO) to wrap the FeO@ coated nanosphere. The prepared catalyst was proven to be very efficient with less than a minute and vey less dosage (15-17 mg) in the adsorptive degradation of Evans blue dye.
