چکیده
|
Tio2 nanosheets (tns) and cobalt doped tio2 nanosheets (co-tns) were prepared by one-pot hydrothermal method# the synthesized samples were identified by various analyses including pxrd, fesem/edx, elemental mapping, drs and raman spectroscopy#the synthesized samples were used to remove of antibiotic tetracycline (tc) under visible and uv irradiation# in the presence of 100 mg tns and co-tns, the percentage removal of 100 mltc (30 mg/l) after 180 minutes of visible light irradiation was 36% and 60%, respectively and it was 77% and 68% respectively after 140 minutes of uv irradiation# co-tns exhibited the higher photocatalytic activity due to faster electron-hole separation and extend the absorption spectrum of tio2 into visible region by cobalt dopant#
