ZnO nano-/micro-crystals with tubular morphology were synthesized by a simple oxidation of a source material mixed with Al, Zn, and Au in air at atmospheric pressure. The tubular morphology was formed when Au was contained in source material. Thus, it was found that Au played an important role in the formation of the tubular morphology. The ZnO crystals with tubular morphology had wurtzite structure and were grown along the [0001] direction. It is proposed that the tubular morphology is formed by the nucleation and the coalescence of nanorods at the six corners of hexagonal base rod.
