Synthesis of TiO2/Carbon Nanoparticle (C-dot) Composites as Active Catalysts for Photodegradation of Persistent Organic Pollutant
ABSTRACT: TiO2/C-dot
composites were synthesised by sol-gel method and investigated as catalysts for photocatalytic
degradation of persistent organic pollutants (perchloroethylene, PCE). The
composites photoluminescence properties was shown by visual analysis and the synthesis
product was characterized by XRD, FTIR, fluorescence spectrophotometer, and
UV-Vis spectrophotometer. Degradation of PCE 0.1% (v/v) in the aqueous phase
was investigated under sunlight irradiation for 2 h. Photodegrade efficiency of
PCE was determined by GC. Composites of TiO2/C-dot 2.5% (w/w) was succesfully
to degrade PCE under sunlight irradiation and its photodegrade efficiency was
up to 89.45%.
