Sažetak
After synthesis of iso-type homojunction (monoclinic-tetragonal) BiVO4 material, this material was enhanced by photodeposition of silver and iron separately. The newly synthesized materials shown to enhance photocatalytic degradation of ciprofloxacin (CIP), antibiotic from the European commission's Watch list. These enhancements happened due to different effects. Photodepsotion of silver enhanced the degradation of CIP, due to the effects of silver lowering the recombination in the material. Iron compound served as a photo-Fenton reagent which activated the production of hydroxyl radicals from hydrogen peroxide in photocatalytic reaction with H2O2. The goal of this study was to get both enhancements (recombination decrease and photo- Fenton activation of H2O2) in one material for an increase in CIP degradation. For that purpose, we combined the synthesis methods for the best photocatalyst from our previous research to see whether we will get the above mentioned combination of effects. The new materials were categorized by XRD, DRS, and SEM. All the new materials showed better solar light photocatalytic performance in CIP degradation then pristine BiVO4.
