主　　题：Graphitic carbon nitride Carbon composite Photocatalysis Photodegradation 

摘      要：An in sitt strategy was introduced for synthesizing carbon modified graphitic carbon nitride(g-C3N4)by using urea/4-aminobenzoic acid(PABA)co-crystal(PABA@Urea)as precursor *** co-calcination of the PABA co-former and the urea in PABA@a Urea co-crystals,C guest species were generated and compounded into g-C3Na matrix in situ by replacing the lattice N of the carbon nitride and forming carbon dots onto its layer *** carbon modification dramatically enhanced visible-light harvesting and charge carrier *** light photo-catalytic oxidation of methylene blue(MB)pollution in water over the carbon modified g-C3Na(C/g-C3Na)was notably *** to 99%of methylene blue(MB)was eliminated within 60 min by the optima sample prepared from the PABA@Urea co-crystal with a PABA content of 0.1%(mass ratio),faster than the degrada-tion rate over bare *** present study demonstrates a new way to boost up the photocatalysis performance of g-C3Na,which holds great potential concerning the degradation of organic dyes from water.
