A simple method for the preparation of hollow ZnO nanospheres for use as a high performance photocatalyst

We have used classical electrospinning and subsequent thermal treatment to successfully fabricate hollow ZnO nanospheres. The hollow ZnO nanospheres were then used to study the degradation of Rhodamine B (RhB) dye and were proven to have excellent photocatalytic activity. The mechanism of formation of hollow ZnO nanospheres and the reason for the high photocatalytic activity were also investigated.
