Photocatalytic properties of ternary magnetic carbon nitride polyoxometalate nanocomposite and its application in reduce removal degradation of dyes pollutants

Graphitic carbon nitride has been considered a very promising semiconductor material , having been intensively studied during the last decade [1]. Graphitic carbon nitride (g-C3N4) has gained remarkable acceptance as a visible-light-driven photocatalyst with a distinctive 2D structure and great stability. Owing to its superior features, g-C3N4 has been engaged in various scientific activities for environmental pollution abatement, production and storage of energy, and gas sensors [2-3]. In this study, ternary magnetic carbon nitride polyoxometalate nanocomposite was synthesized and its photocatalytic activity for degradation of organic pollutants were investigated. In this synthetic process, g-C3N4 was obtained with urea by a thermal treatment and subsequent modified with magnetic composite and polyoxometalate. The surface morphology and chemical structure of the nanocomposite were characterized by FTIR, VSM, XRD and SEM. The resulting nanocomposite exhibited high photocatalytic activity for degradation of organic pollutants such as Methylene blue (MB), Rhodamine B (RhB )and Methyl orange (MO). Moreover, this nanocomposite as photocatalyst shows recyclable adsorption and stable performance after being used several times.
