Abstract
In this paper, BaZrO3 was chemically synthesized using liquid NH3 as precipitating agent and green synthesized using Moringa oleifera (M. oleifera) leaf extract without the addition of liquid NH3. X-ray diffractograms confirmed the cubic nature of the samples with.(110) preferential growth. XPS studies ascertain the existence of Ba, Zr and O in the green synthesized sample. Decreased band gap was observed for the green synthesized sample. Ba-O stretching vibrations were observed respectively at 480 and 487 cm−1 for the chemically synthesized and green synthesized samples. The green synthesized BaZrO3 exhibits better degradation efficiency of 84.1% after 90 min against CR dye. The green synthesized BaZrO3 nanoparticles exhibited excellent antimicrobial activity against E. coli and A. terreus. The third order nonlinear absorption coefficient and susceptibility values of the green synthesized BaZrO3 were found to be equal to 3.05 × 10−6 cm/W and 4.67 × 10−8 esu, respectively.
