Novel Formation of Bi@BiFe-glycolate Hollow Spheres and Their Conversion into Bi2O3/BiFeO3 Composite Hollow Spheres with Enhanced Activity and Durability in Visible Photocatalysis

Abstract

In recent years, materials with extraordinary hollow structure have been widely studied beacause of its enormous potential in many research fields such as advanced energy conversion and storage. To design and synthesize a innovative hollow structure via a facile method is the very key to enhance performance in application of advanced energy materials. In this research, we report a novel hollow Passion fruit-like Bi@BiFe-glycolate microspheres (3.5 μm) which is constructed with BiFe-glycolate nanosheets and Bi nanoshperes. They are designed and synthesized via a facile one-pot solvothermal method and a mechanism of “spit and swallow” process is presented to describe the reaction accordantly. Besides, the Bi2O3/BiFeO3 photocatalyst obtained by annealing the Bi@BiFe-glycolate precursors in air atmosphere exhibits an enhanced photocatalytic activity and cycling stability under visible light irradiation due to its special morphology and band structure. The photocatalyst can also be recycled conveniently owing to its magnetism property. In general, this work has a potential possibility of reference in both nanomaterial synthetic method and photocatalytic performance improvement.
