Abstract
To overcome the drawback of UV light response in La2Ti2O7 nanosheets, novel up-conversion carbon quantum dots (CQDs) with visible light response have been introduced on the surface of La2Ti2O7 for efficient enhancement of photocatalytic performance. The resulted CQDs/La2Ti2O7 samples were characterized by XRD, TEM, FT-IR, XPS and UV-vis, respectively. Rhodamine B (RhB) solution was chosen as the target organic pollutant to evaluate the photocatalytic activity under visible light irradiation. The results indicated that 5â¯wt% loading of CQDs composite exhibited the best performance. Both the up-converted photoluminescence behavior and their electron capturing ability of CQDs are considered as the main reasons for the enhanced photocatalytic abilities.
