摘      要：We developed an one-step hydrothermal method to synthesize carbon-nitrogen quantum dots(CNQDs) with oxygen-rich functional *** sample was characterized by TEM,AFM,FT-IR,XPS,UV-vis absorption and PL *** 0/C and N/C atomic ratio of typical CNQDs with diameters of 3-6 nm are ca.0.4 and 0.2,*** noble metal cocatalyst,the photocatalytic H2production rate of CNQDs/TiO2nanofibers(NFs)(112.4 μmol h-1g-1) is 1.8 times higher than that of *** good absorption of light contributes to the enhanced photocatalytic *** CNQDs could be promising in biomedical imaging,optical data recording storage and photo/electrocatalysis,etc.
