Abstract

Flower-like Bi₂O₂CO₃ and g-C ₃N₄-Bi₂O₂CO₃ microspheres with a high adsorption ability were synthesized using a facile method, and their dye-induced photosensitized degradation activity under visible light irradiation was evaluated. The as-synthesized samples were characterized by XRD, FT-IR, FESEM, TEM (HRTEM), UV-vis DRS and nitrogen adsorption-desorption techniques. It was found that the activity of Bi₂O₂CO ₃ was significantly enhanced due to the generation of g-C ₃N₄-Bi₂O₂CO₃ heterostructures. The dye-sensitization and the presence of g-C ₃N₄ are beneficial for the visible-light excited process. The enhancement of photocatalytic performance is ascribed to the proper matching of the energy levels of the dye, Bi₂O₂CO₃ and g-C₃N₄ that facilitates the separation and transfer of photogenerated electrons and holes at the heterojunctions. The results of the present study give insights that are beneficial for the design of heterostructured materials.
