A simple hydrothermal method has been used to synthesize 3D ZnO architectures without any surfactants. The assemblies were composed of thin nanoplates with the thickness of about 35nm. X‐ray diffraction analysis (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and photoluminescence (PL) characterized the structure, morphology and optical property of products. The thickness of plates and assembly pattern can be controlled by adjusting the experimental parameters. Furthermore, these ZnO nanoplate assemblies exhibited enhanced photocatalytic activity in the degradation of methylene blue (MB). (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
