Synthesis and Property Examination of Er₂FeSbO₇/BiTiSbO₆ Heterojunction Composite Catalyst and Light-Catalyzed Retrogradation of Enrofloxacin in Pharmaceutical Waste Water under Visible Light Irradiation.

ABSTRACT: A new photocatalyst, Er₂FeSbO₇, was prepared by solid phase sintering using the high-temperature synthesis method for the first time in this paper. Er₂FeSbO₇/BiTiSbO₆ heterojunction (EBH) catalyst was prepared by the solvent thermal method for the first time. Er₂FeSbO₇ compound crystallized in the pyrochlore-type architecture and cubelike crystal system; the interspace group of Er₂FeSbO₇ was Fd3m and the crystal cellular parameter a of Er₂FeSbO₇ was 10.179902 Å. The band gap (BDG) width of Er₂FeSbO₇ was 1.88 eV. After visible light irradiation of 150 minutes (VLGI-150min) with EBH as a photocatalyst, the removal rate (RR) of enrofloxacin (ENR
