Abstract
Tellurium-cobalt/polybutylene terephthalate (Te-Co/PBT) and Te/PBT nanocomposites were pre-pared via solution casting method. The morphological study presented that both Te and Te-Co nanoparticles (NPs) are well embedded inside the polymer matrix. The Te NPs are round in shape having size less than 150 nm. While Te-Co NPs are in agglomerated form. The size of agglomerated NPs are below 400 nm. The formation of NPs was also confirmed by Fourier-transform infrared spectroscopy and energy-dispersive X-ray spectroscopy. thermogravimetric analysis presented that the thermal stability of nanocomposites was higher than neat PBT. Photodegradation study presented that the Te-PBT and Te-Co/PBT nanocomposites significantly degraded the bro-mothymol blue dye in aqueous medium. The neat PBT degraded about 7% and 21% of dye while Te(40 wt.%)/PBT and Te/Co(40 wt.%)/PBT degraded about 51% and 71%, and 56% and 77% dye, respectively within 2 and 8 h irradiation time.
