Study on the synthesis of g-C₃N₄/CoFe₂O₄/Reduced graphene oxide material and its application as photocatalyst

Abstract

In this study, the g-C3N4/CoFe2O4/Reduced graphene oxide composites were successfully synthesized by the co-precipitation method combined with mixed phase mixture. The obtained results from characterization methods such as XRD, SEM, FT-IR, EDX,… showed that the composite has a high structure and crystallinity, and spinel ferrite particles were dispersed fairly evenly onto reduced graphene oxide sheets as well as layers of g-C3N4. The existence of Co/Fe-O and Co-O-C bonds in materials was determined. The photocatalytic activity of g-C3N4/CoFe2O4/Reduced graphene oxide (GCN/CF-rGO) was estimated through the degradation of Tetracycline (TC) in aqueous solution. TC decomposition efficiency is up to 95% after 240 minutes of reaction and is higher than that of each component material. GCN/CF-rGO is a potential catalyst for effective application in TC decomposition reaction under visible light and has the ability to implement treatment in practice.
