چکیده
In this paper, graphitic carbon nitride (g-C3N4) 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-C3N4 and prevent charge recombination in the as-prepared photocatalyst. The useful features of this method to prepare P-doped g-C3N4 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-C3N4 nanosheets with ultrasound, which leads to an increase in photodegradation of Tartrazine under visible light.

چکیده [English]
در این مقاله، کربن نیترید گرافیتی از طریق پیرولیز مستقیم ملامین تهیه شد و سپس برای سنتز نانو ورقه های کربن نیترید گرافیتی دوپ شده با فسفر در اسید فسفریک با اولتراسونیک مورد استفاده قرار گرفت. این روش ساده به افزایش جذب نور، تغییر خواص الکترونیکی کربن نیترید گرافیتی و جلوگیری از باز ترکیب بار در فوتوکاتالیست تهیه شده کمک کرد. از ویژگی های مفید این روش در تهیه نانو ورقه های کربن نیترید گرافیتی دوپ شده با فسفر می توان به سادگی، زمان سنتز کوتاه، مقرون به صرفه و سازگار با محیط زیست بودن آن اشاره کرد. مطالعه حاضر توانایی اسید فسفریک برای سنتز نانو ورقه های کربن نیترید گرافیتی دوپ شده با فسفر را با استفاده از امواج اولتراسونیک نشان می دهد، که این امر منجر به افزایش تخریب نوری تارترازین تحت نور مرئی شد.
