Özet
Currently, the widespread use of antibiotics and their improper disposal have led to environmental concerns. The design of carbonaceous TiO2 composites has gained interest in eliminating antibiotic pollution as potential photocatalysts. The present study employed a simple two-step strategy to prepare a series of carbonaceous TiO2 (C-PANI-TiO2) composites based on the carbonized form of polyaniline (PANI) via in-situ chemical oxidation polymerization and thermal treatment in an inert atmosphere. Besides, a systematic characterization was performed using structural, morphological, optical, and surface parameter tools. XRD analysis revealed the existence of mixed anatase and rutile phases of TiO2 in C-PANI-TiO2 composites. The carbonized structure of C-PANI-TiO2 composites was confirmed by Raman spectroscopy. UV-DRS analysis indicated that the carbonization process shifted the absorption band towards the visible region. The morphological feature of C-PANI-TiO2 composites was dependent upon the initial molar ratios of aniline (ANI) and TiO2 in the composites. The photocatalytic activities of C-PANI-TiO2 composites were evaluated by the photocatalytic degradation of ciprofloxacin (CIP) and ceftriaxone (CEF). The highest photocatalytic efficiency was around 96 % (120 min) and 82 % (60 min) for CIP and CEF, respectively, using C-PANI-TiO2 composite at the initial mole ratios of ANI:TiO2 of 1:8 (CPT-81 composite). The recyclability and reusability tests, conducted up to four cycles, highlighted an efficiency of 82 % even after four cycles of C-PANI-TiO2 composites, as effective photocatalysts.
