摘要：Three dimensional (3D) hierarchical flower-like ZnO micro-/nanospheres with controlled morphology and dimensionality were synthesized successfully through a facile aqueous solution route at low temperature, in which the hexadecyl trimethyl ammonium bromide (CTAB) and ascorbic acid (AA) were used as structural auxiliaries. Since the well-crystallized wurtzite and composed of interconnected nanosheets/nanorods with the uniform size of 1 similar to 2 mu m, the as-prepared 3D ZnO exhibited an outstanding photocatalytic ability to degrade rhodamine B (RhB) under UV radiation, which could be attributed to the enormous generation and effective separation of electrons and positive holes due to the particular properties of 3D ZnO nanomaterials.
