Facile Solvent-Less Preparation, Characterization and Investigation of Photocatalytic Properties of Pr۶O۱۱ Nanostructures

چکیده مقاله

Pr6O11 nanostructures were synthesized through a facile solvent-less method. Nanostructures were prepared by heat treatment in air, using [Pr L(NO3)2]NO3 (L = bis-(salicyladehyde)-1,4-butadiimine Schiff base ligand), as new precursor, which was obtained by a solvent-free solid–solid reaction from praseodymium nitrate and Schiff base ligand. The as-obtained nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and ultraviolet–visible (UV–vis) spec-troscopy. The obtained results demonstrated that utilizing of this precursor is suitable choice for preparation of Pr6O11 nanostructures with very uniform sphere-like morphology. The photocatalyst activity of as-obtained Pr6O11 was also examined by degradation of 2-naphthol as organic contaminant under ultraviolet light irradiation.
