Self-assembly 3D porous ZnO nanostrip clusters are prepared through a calcinating hydroxide zinc carbonate precursor route. The fabrication of the precursor involves oriented attachment and self-assembly processes. The obtained porous 3D ZnO architectures show obvious structure enhanced photocatalytic performance, which can be attributed to the special structural feature of an open and porous surface layer that significantly facilitates the diffusion and mass transportation of organic molecules and oxygen species during the photochemical reaction.
