Magnetically retrievable Ce-doped FeO nanoparticles as scaffolds for the removal of azo dyes.

Considering the significant impact of magnetically retrievable nanostructures, herein, FeO and Ce-doped FeO nanoparticles were employed as scaffolds for the removal of the Reactive Black 5 (RB5) azo dye. We synthesized the Ce-doped FeO nanoparticles hydrothermal treatment at 120 °C for 10 h with varying cerium concentrations (1.5-3.

Photophysical deactivation behaviour of Rhodamine B using different graphite materials.

In the present work, an attempt has been made to elucidate the structural features of synthesized graphite materials, , expanded graphite (EG) and an expanded graphite/silver nanoparticles (EG/AgNPs) nanocomposite. In order to obtain knowledge about the functional groups present, the interlayer spacing between the carbon layers, topographical features, and the characterization of the materials were carried out using Fourier-transformer infrared spectroscopy, X-ray diffraction, Raman spectroscopy, field emission scanning electron microscopy-energy dispersive X-ray spectroscopy and atomic force microscope. Furthermore, the quenching efficiency of the synthesized graphite materials was also compared using Rhodamine B (Rhd B) as a fluorescent probe.
