Modeling adsorption and photocatalytic treatment of recalcitrant contaminant on multi-walled carbon/TiO nanocomposite.

A nanocomposite photocatalyst consisting of titanium dioxide (TiO) supported on multiwalled carbon nanotubes (MWCNTs) has been successfully prepared and used for the treatment of wastewater contaminated with tetracycline (TC), a recalcitrant antibiotic pollutant. The TiO/MCNT composites were prepared by a simple evaporation-drying method. The properties of MWCNT/TiO were optimized by dispersing different amounts of TiO onto MWCNT.
