چکیده
|
Tetragonal zirconia (t-zro2) nanoparticles were synthesized from the zirconium chloride using the co-precipitation technique and characterized by various measurement techniques. fesem analysis further revealed spherical shaped nps and hr-tem analysis determined the size of the particles in the range of 14.5 nm. the band gap energy was estimated 4.0 ev. the uv (350 nm) emission was observed from pl spectrum. the photocatalytic degradation of the as-prepared zro2 nanoparticles were studied under uv light irradiation using ciprofloxacin (cip) as a model organic pollutant. results showed that 50% degradation were achieved within 15 min.
