In this paper, graphitic carbon nitride (g-C۳N۴) was prepared by direct pyrolysis of melamine and then used to synthesize P-doped graphitic carbon nitride nanosheets with ultrasound in phosphoric acid. This simple method helps increase the trapping of light, change the electronic property of g-C۳N۴ and prevent charge recombination in the as-prepared photocatalyst. The useful features of this method to prepare P-doped g-C۳N۴ nanosheets are its simplicity, short synthesis time, economical and environmentally friendly. The present study demonstrates the ability of phosphoric acid to synthesize P-doped g-C۳N۴ nanosheets with ultrasound, which leads to an increase in photodegradation of Tartrazine under visible light.
