Flower-like MWCNTs/Bi2O2CO3 composites with enhanced photocatalytic activity under simulated solar light irradiation

Flower-like MWCNTs/Bi2O2CO3 composites composed of Bi2O2CO3 nanosheets and MWCNTs were prepared by a simple solvothermal method. These composites all showed higher photocatalytic activities than pure Bi2O2CO3 for the degradation of RhB or 4-CP under simulated solar light irradiation. Among them, the MWCNTs/Bi2O2CO3 composite with 3 wt% MWCNTs (M/B-3%) exhibited the highest photo catalytic activity and excellent stability. The enhanced photocatalytic performance could be attributed to the enhanced light absorption and efficient separation of photogenerated charge carriers. (C) 2016 Elsevier B.V. All rights reserved.
