Synthesis of Ti doped Ca-BiFO for the enhanced photodegradation of moxifloxacin

In recent years, the continuously increasing demand for wastewater treatment has increased research on perovskite-based materials with narrow band gaps. Titanium-doped calcium bismuth ferrites (CaBiFe 1− x Ti x O 3 x = 0.00-15%) were successfully synthesized using the co-precipitation method. X-Ray diffraction data and SEM micrographs revealed the phase purity and nanocrystalline nature (rhombohedral lattice) of the CaBiFe 1− x Ti x O 3 x = 0.00-15% samples. The energy band gap of the Ca-BiFO 3 nanoparticles was tuned by the substitution of Ti 4+ ions in the range of 2.96-2.1 eV. The Ti 4+ substituted Ca-BiFO 3 nanoparticles exhibited much higher photocatalytic performance for antibiotics (moxifloxacin) under controlled UV-visible light irradiation compared to pristine Ca-BiFO 3 nanoparticles. The high concentration of moxifloxacin in water causes environmental problems, such as antibacterial resistance in bacteria and threats to ecology. The CaBiFe 85% Ti 15% O 3 nanoparticles showed 89.16% moxifloxacin degradation after irradiation for only 60 min. The significant changes in the photocatalytic properties of the sample were due to the aliovalency of Fe 3+ and Ti 4+ , and differences in ionic radii and oxygen vacancies. In recent years, the continuously increasing demand for wastewater treatment has increased research on perovskite-based materials with narrow band gaps.
