摘要：
A CQDs/CoO/g-C3N4 nanocompo site used for photocatalytic degradation was designed and fabricated in this paper. The effects of carbon quantum dots (CQDs) content and synthesis temperature on photocatalytic properties of nanocomposites were studied. The results show that the solar energy utilization efficiency of CQDs/CoO/g-C3N4 nanocomposite is twice that of pure g-C3N4 when the content of CQDs is 4.5 wt%. The improvement of photocatalytic performance of nanocomposite is mainly attributed to the synergistic effect of the junction/interface between g-C3N4, CoO and CQDs.
