| 中文摘要 | a facile hydrothermal synthesis route to n and s, n co-doped graphene quantum dots (gqds) was developed by using citric acid as the c source and urea or thiourea as n and s sources. both n and s, n doped gqds showed high quantum yield (78% and 71%), excitation independent under excitation of 340-400 nm and single exponential decay under uv excitation. a broad absorption band in the visible region appeared in s, n co-doped gqds due to doping with sulfur, which alters the surface state of gqds. however, s, n co-doped gqds show different color emission under excitation of 420-520 nm due to their absorption in the visible region. the excellent photocatalytic performance of the s, n co-doped gqd/tio2 composites was demonstrated by degradation of rhodamine b under visible light. the apparent rate of s, n: gqd/tio2 is 3 and 10 times higher than that of n: gqd/tio2 and p25 tio2 under visible light irradiation, respectively. |
