▎ 摘 要
This research reported electro-static junctions between carbon nanotubes (CNT) and graphitic carbon nitride (CCN) with enhanced photocatalytic properties. The CNT and CCN formed the CTCN (CNT/CCN) by the electro-statistic driving force under hydrothermal methodology. The materials fabrication was confirmed by using different analyzing techniques such as SEM, TEM, XRD, and FTIR (etc). Also, the photocatalytic ability was studied by the degradation of R-610 under visible light irradiation. The CTCN-1 possess the higher degradation rate 0.0105 min(-1) and higher current density 0.19 mu A/cm(2) as compare to other, CTCN-2 (0.0088 min(-1), 0.16 mu A/cm(2)), CTCN-3 (0.0065 min(-1), 0.12 mu A/cm(2)) and CCN (0.0035 min(-1), 0.10 mu A/cm(2)). The combining of CNT with CCN in a specific amount reduces the structure defects in graphitic carbon nitride by reducing the charge recombination ability. Ion-trapping experiments showed that superoxide radicals and holes are the most generated and effective photogenerated species to accomplish the degradation of R-610 (rhodamine-610) under visible light irradiation.
