Bi 2 O 3 Modifi ed Floatable Hollow Glass Microspheres Supported TiO 2 to Construct II-Scheme Heterojunction for Photocatalytic Degradation of Tetracycline Hydrochloride

Abstract
Photocatalysis technology has garnered signifi cant attentions for addressing water pollution issues, however, conventional
photocatalysts face great challenges such as poor recoverability, low light utilization rates, and severe caking that hinder their
widespread use. This study presents the development of fl oating Bi 2 O 3 /TiO 2 /HGM (BTH) photocatalysts utilizing hollow
glass microspheres (HGM) as a supporting material. The optimized heterojunction of BTH-0.3 achieves an 83.9% removal
rate of tetracycline hydrochloride within 60 min irradiation under simulated sunlight, surpassing the 77.3% achieved by
TH-2 loaded with only TiO 2 and the 62% achieved by pure Bi 2 O 3 . Furthermore, BTH-0.3 exhibits outstanding photocatalytic
performance across varying solution pH levels and diverse water matrices. Moreover, consistent tetracycline hydrochloride
removal rates were observed over four consecutive degradation cycles, demonstrating its excellent reusability. This research
off ers a promising approach with practical potential for addressing water pollution challenges via photocatalytic technology.
