Self-assembly of ZnO nanoplates into microspheres

The chemical fabrication of materials with a controllable size and shape has attracted considerable interest due to the obvious importance of size and shape of materials in determining their properties [1, 2, 3, 4, 5]. Recently, the research on the structures of materials is expanding rapidly to the assembly of nanoparticles into two-dimensional (2-D) or three-dimensional (3-D) ordered superstructures [6, 7, 8]. However, few reports on the self-assembly nanoplates into microspheres have been made to date.
As a wide bandgap semiconductor material with a large excitation binding energy, ZnO has promising applications in catalytic, electrical, optoelectronic and photochemical fields [9, 10, 11]. It is known that the properties of ZnO depend closely on its microstructures, thus its surface area and morphology (how the crystals are stacked) have a crucial role in many applications of ZnO . Therefore, the development of morphologically controllable synthesis of ZnO with different...
