Influence of Calcination Temperature on Ciprofloxacin Photodegradation by Vanadium Pentoxide / Graphitic Carbon Nitride Photocatalyst

Abstract

The employment of vanadium pentoxide (V2O5) as a photocatalyst has been widely utilized owing to its promising supercapacitor properties for photocatalysis applications under visible light without any alteration. Up to date, there has yet to be a report on the investigation of calcination temperature effect on V2O5 and graphitic carbon nitride (g-C3N4) combination photocatalyst synthesis for ciprofloxacin (CIP) photodegradation. In this study, the V2O5 / g-C3N4 photocatalyst is synthesized using simple and facile calcination process. The properties of the synthesized V2O5 / g-C3N4 were evaluated in terms of porosity, surface morphology and composition elements, and its band gap value to well understand its’ behaviour and interaction with CIP pollutants. The best synthesis conditions for V2O5 / g-C3N4 photocatalyst on CIP photocatalysis were at 500 °C (500VC) with 90.17 % CIP photodegradation performance. This research has provided a useful future reference in the field of photocatalysis research.
