Efficient Photocatalytic Degradation of Aqueous Atrazine over Graphene-Promoted g-C3N4 Nanosheets

Atrazine is a systemic herbicide widely used in weed control. In recent years, it has been largely detected surface and groundwater several locations all over the world. Photocatalysis green sustainable technology with huge application prospects pollution control degradation of organic water pollutants. this work, photodegradation aqueous atrazine was investigated pristine graphitic carbon nitride (g-C3N4) synthesized via urea pyrolysis graphene/g-C3N4 composite situ growth method involving direct deposition g-C3N4 nanosheets on graphene surface. The obtained photocatalysts were characterized using transmission scanning electron microscopy, Fourier-transformed infrared spectroscopy, UV-visible photoluminescence X-ray diffraction, area measurements. It demonstrated that material exhibited remarkable photocatalytic properties for efficient under visible light at ambient temperature. After 5 h reaction, conversion reached 100% presence composite, while allowed 40% same conditions, thus demonstrating positive effect activity g-C3N4. Moreover, shown to keep its even when recycled five times, proving stability potential be industrial scale.
