Controllable synthesis of perovskite-like PbBiO2Cl hollow microspheres with enhanced photocatalytic activity for antibiotic removal

Abstract

Novel perovskite-like PbBiO2Cl materials with hollow and porous sphere-like structure were successfully synthesized with polyvinyl pyrrolidone (PVP) and reactable ionic liquid 1-hexadecyl-3-methylimidazolium chlorine ([C16mim]Cl) complex system. The TEM had been employed to characterize the hollow-porous structure formed by the double regulation of ionic liquid and PVP. The achieved hollow-porous PbBiO2Cl sphere-like photocatalyst showed excellent photocatalytic activity towards the degradation of colorless antibiotic agent ciprofloxacin (CIP) and tetracycline (TC) under visible-light irradiation. The enhanced photocatalytic performance of PbBiO2Cl materials was mainly derived from the porous and hollow structure, which enables the larger specific surface area and faster interfacial charge separation. Moreover, based on the analysis of XPS valence spectra, electron spin resonance (ESR) and free radical trapping experiment, the main active species were determined to be hole and superoxide radical during the photocatalytic degradation process. According to the results of characterizations and the comparative test, the possible growth and photocatalytic reaction mechanism were proposed.
