摘要：In this work, NPC (nanoporous carbon) is purposely employed to accommodate the semiconductor CdSe QDs (quantum dots) in the absence of any capping agent to facilitate the visible-light photocatalyst CdSe QDs@NPC composite. CdSe QDs@NPC composite has been achieved by the facile method of the incipient-wetness deposition, and furthermore characterised by powder X-ray diffraction, inductively coupled plasma atomic emission spectroscopy, X-ray photoelectron spectroscopy, Brunauer-Emmett-Teller, transmission electron microscopy (TEM) and highresolution TEM (HRTEM). The results of TEM and HRTEM show that CdSe QDs are implanted into NPC and bound to several nanometres. Both X-ray diffraction and HRTEM indicate that the as-synthesised CdSe QDs belong to the cubic phase. The photocatalytic performance of CdSe QDs@NPC composite has been evaluated by degrading the RhB under visible-light irradiation. NPC as electron acceptor and transport channel can enhance the synergism of CdSe and NPC by improving the electron-hole separation. Furthermore, the photocatalytic mechanism exhibits that h(+) and O-2(- center dot) species are the decisive, active species in the degradation process of RhB.
