Abstract

Graphitic g-C₃N₄-WO₃ composite was synthesized simply by decomposing melamine in the presence of WO₃ at 500 °C. The obtained material was characterized by XRD, SEM, IR and XPS. The results showed that the as-prepared composite exhibits orthorhombic WO ₃ phase coated by g-C₃N₄ and the g-C ₃N₄ decomposed completely with N-doped WO₃ remaining at elevated calcination temperatures. The photocatalytic activity of the composite was evaluated by the photodegradation of methylene blue under visible light. An enhancement in photocatalytic activity for the graphitic g-C₃N₄-WO₃ composite compared to the conventional nitrogen-doped WO₃ was observed, which can be attributed to the presence of g-C₃N₄ in the material.
