Abstract
Nanorod graphitic carbon nitride (g-C3N4) was synthesized by reacting melamine (C3H6N6) with trithiocyanuric acid (C3H3N3S3) in distilled water for 10 h at room temperature. The resulting mixture was calcined at 550°C for 2 h in an electric furnace under an air atmosphere. Nanorod g-C3N4/Ag3PO4 composites were prepared by adding nanorod graphitic carbon nitride (g-C3N4) powder, silver nitrate (AgNO3), ammonia (NH3·H2O, 25.0-30.0%), and sodium hydrogen phosphate (Na2HPO4) to distilled water. The samples were characterized via X-ray diffraction, scanning electron microscopy, and Fourier-transform infrared spectroscopy. The photocatalytic activities of the nanorod g-C3N4/Ag3PO4 composites were demonstrated via the degradation of organic dyes, such as methylene blue and methyl orange, under blue light-emitting diode irradiation and evaluated using UV-vis spectrophotometry.
