Abstract
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.
