Sažetak
The study explores the potential of novel composite photocatalyst made of TiO2 and conductive polymer poly(3, 4- ethylenedioxythiophene) (TiO2-PEDOT) for the removal of bisphenol A (BPA), a water contaminant of emerging concern. TiO2-PEDOT with different PEDOT contents were prepared by oxidative chemical polymerization of (3, 4- ethylenedioxythiophene) (EDOT) in the presence of TiO2, using either (NH4)2S2O8 or FeCl3 as oxidants, to study their role on photocatalytic properties. Composites were characterized for their composition and morphology, as well as surface, structural and optical properties. Composites have core-shell-like morphology, possessing homogeneous polymer distribution over TiO2 surface. Composites have specific surface area comparable to benchmark material (TiO2 P25), while band gaps and recombination rates are significantly lower. The photocatalytic activity was evaluated under simulated Solar irradiation for the removal of BPA. The observed effects were correlated with the changes of process parameters (PEDOT content, photocatalyst loading and initial pH) using response surface modeling approach. TiO2- PEDOT showed higher effectiveness than benchmark material TiO2 P25. The influence of various water matrix constituents (carbonates, nitrates, sulphates, chlorides, phosphates and natural organic matter) on BPA removal were studied as well, and were found to be detrimental to BPA removal through scavenging bulk and surface hydroxyl radicals.
