elimination of levofloxacin antibiotic from aqueous solutions over bismuth silicate and bi2moo6 nanophotocatalysts designed via sono-solvothermal methods

In the present study, bismuth silicate (bi2sio5) and bismuth molybdenum oxide (bi2moo6) nanophotocatalysts have been prepared by one-pot sono-solvohermal synthesis for the elimination of lecofloxacin (lvo). crystallographic and morphological analyses are used to demonstrate the true synthesis of nanophotocatalysts and the discussion of results gained. as-synthesized bi2moo6 showed higher remediation potential towards lvo pollutant. bi2moo6 could remediate 30 mg/l lvo up to 79% (corresponding concentration: 26.1 mg/l) during 150 min (60 min dark + 90 min light). but, the remediation capability of bi2sio5over 30 mg/l lvo was calculated to be 14% (corresponding concentration: 6.2 mg/l) at the same condition. as a result, he remediation potential of bi2moo6 nanophotocatalyst is 5.67 times of bi2sio5 owing to its suitable band gap, effective light harvesting and probably proper surface area.
