In this research, an innovative Z-scheme vanadium pentoxide (V 2 O 5 )/graphitic carbon nitride (g-C 3 N 4 ) photocatalyst was synthesised using a facile thermal treatment method, and its photodegradation performance and physicochemical properties were evaluated. The heterostructure provided high Brunauer–Emmett–Teller surface area and pore volume, which encouraged charge carrier separation and transfer, as well as supplied abundant micro-mesoporous structures and active sites for photocatalytic redox reactions. The successful incorporation of V 2 O 5 between g-C 3 N 4 layers can be proven by proposing the synthesis mechanism, as well as conducting morphology, crystal structure, elemental, and chemical analysis through scanning electron microscopy, X-ray diff raction, energy dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy, respectively. Using these combined photocatalysts, ciprofl oxacin (CIP) was successfully degraded up to 90.17% removal effi ciency in the visible-light spectrum. The superior photocatalytic activity of g-C 3 N 4 composite over V 2 O 5 is primarily due to its increased light absorption capacity, as well as increased surface area, pore size, and volume, eff ective charge transfer, and optimal band alignment between g-C 3 N 4 and V 2 O 5 . This research provides a signifi cant future perspective for the utilisation of Z-scheme V 2 O 5 /g-C 3 N 4 heterojunction photocatalyst for water treatment, especially those involving endocrine-disrupting compounds and antibiotics like CIP.
