文摘

Carbon quantum dots (CQDs) coupled with Fe-doped g-C3N4 to prepare a binary composite photocatalyst was obtained. Sucessfully grafted Fe(III) species on the surface of CQDs/Fe-doped g-C3N4 via a facile impregnation method. As the cooperation between the IFCT effect and the photo-Fenton reaction, OH active species would be generated. The mechanism of the generation of OH was clarified by solid EPR and EPR trapping technology.
