Doping of boron in TiO2 catalyst: Enhanced photocatalytic degradation of antibiotic under visible light irradiation

Year 2017, Volume: 2 Issue: 1, 18 - 27, 16.03.2017

Abstract

A series of
B-doped anatase TiO2 catalysts have been synthesized by solvothermal
method and the photocatalytic activity toward a fluoroquinolone antibiotic (ciprofloxacin)
has been investigated. The results showed that the boron doping not only
reduced the band gap energy, it also improved the
photocatalytic activity of TiO2 towards the selected antibiotic
under visible light irradiation. The effects of solution pH, catalyst dosage
and the presence of process enhancer/inhibitors on the photoactivity were examined.
Response surface methodology was successfully utilized to model and optimize the
photocatalytic process with high correlation (R2 = 0.9960). The
degrees of boron doping and visible light active mechanism have also been studied.
Compared with raw TiO2 boron doped catalysts exhibit excellent
photostability and photodegradation ability of ciprofloxacin under visible
light irradiation.
