Abstract The elimination of organic pollutants from water poses a
considerable challenge in environmental remediation in this study, the
potential of ZnS-ZnO semiconductors as efficient photocatalysts for
degrading aqueous solutions of ceftriaxone (CEF) was investigated in a
mini-UV reactor. The ZnS-ZnO heterostructures were synthesized via the
hydrothermal method and characterized using analytical techniques (SEM,
FTIR), demonstrating considerable photocatalytic activity (UV-Vis
monitoring), with degradation of CEF occurring within a relatively short
period of time. Keywords: ceftriaxone, degradation, photocatalysis, ZnS
