Induced abundant oxygen vacancies in Sc2VO5−δ/g-C3N4 heterojunctions for enhanced photocatalytic degradation of levofloxacin† † Electronic supplementary information (ESI) available. See DOI: https://doi.org/10.1039/d2ra07484b

ABSTRACT: Sc2VO5−δ/g-C3N4 heterojunctions (SVCs) with abundant oxygen vacancies (OVs) were synthesized by ultrasonic exfoliation combined with the thermal etching method. The structures, OVs and spatial separation of the photogenerated carriers were systematically characterized. The results manifested that the SVCs were successfully constructed via the strong interaction between g-C3N4 (CN) and Sc2VO5−δ (SV). The SVCs possessed a higher concentration of OVs than that of pristine CN and SV. The formation of the SVC heterostructures and the optimization of the OVs were the two major factors to accelerate the separation of the charge carriers and finally to improve the photocatalysis performance. The as-prepared 10%SVC (containing 10 wt% of SV) catalyst exhibited the highest OV concentration and the be
