Abstract

The development of an efficient and photostable heterostructured photocatalyst has attracted a great deal of attention for the degradation of organic pollutants under visible light. Herein, we have developed a highly efficient graphitic carbon nitride/zinc oxide/iron oxide (g C3N4/ZnO/Fe2O3) ternary composite photocatalysts that were prepared by a simple and cost-effective calcination method. The crystalline structure, functional groups, morphological and optical properties of the as-prepared g-C3N4/ZnO/Fe2O3 (GZF) ternary composite
were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy and UV–Vis diffuse-reflectance spectroscopic techniques. The GZF composite reveals enhanced methylene blue (MB) degradation with good photostability of 100% retention rate even after 5
cycles under visible light irradiation. Moreover, GZF composite was degraded 94% of MB after 120 min under visible light irradiation which was almost 6.6- and 3.1-fold higher than individual g-C3N4 (GCN) and g-C3N4/ZnO (GZ). The
results suggest that the composites of g-C3N4 with metal oxide under visible light significantly enhance the electron transfer process.
