BiOCl Hierarchical Nanoflowers with Superior Mixed-dye Photodegradation Activity

Abstract

3D BiOCl hierarchical nanostructures assembled with nanosheets have been successfully synthesized via a facile solvothermal route with Bi(NO3)3, KCl, poly(vinylpyrrolidone) (PVP), and diethylene glycol (DEG). Photocatalytic experiment illustrated that the as-synthesized BiOCl nanoflowers exhibited superior photocatalytic activity than that of BiOCl microrods and Degussa P25 in the degradation of single and mixed dye solutions under UV irradiation, which has not been reported previously. Besides, the stability of the product in mixed organic dye photodegradation process was also investigated for the first time.

CMC/BiOCl 3D Hierarchical Nanostructures with Exposed {001} Facets and Its Enhanced Photocatalytic Activity

“…Mi demonstrated that 3D nano‐velvet substructures enhanced the light harvest and molecule adsorption capability, and the efficacious photocatalytic and water splitting systems was established . Cao proved that BiOCl nanoflowers exhibited superior photocatalytic activity than that of BiOCl microrods in the degradation of single and mixed dye solutions . As a result, BiOCl with exposed {001} facets and 3D hierarchical nanostructures can enhance the BiOCl photocatalytic activity,, However, it is rarely reported to get better photocatalytic activity by the synergetic effects of 3D hierarchical nanostructures and exposed {001} facets.…”
