Direct conversion of Bi nanospheres into 3D flower-like BiOBr nanoarchitectures with enhanced photocatalytic properties

Herein, we demonstrate for the first time the direct conversion of metallic Bi nanospheres into three-dimensional (3D) flower-like BiOBr nanoarchitectures at room temperature, which exhibited much higher photocatalytic performance for the photodegradation of organic dyes than 2D BiOBr nanoplates under visible light irradiation.
