The effects of the addition of crystalline Mo3VOx oxides (MoVO) seeds on an assembly of pentagonal [Mo6O21]6鈥?/sup> building units with Mo and V octahedra for forming MoVO were investigated. In the absence of the seeds, the crystal phase of formed MoVO depended on the pH of the preparative solution, while the crystal phase of the formed MoVO was decided by the phase of the MoVO seeds used irrespective of the pH. Interestingly, MoVO were formed even in the pH condition where no crystals were formed in the absence of the seeds. It was shown by X-ray diffraction, scanning transmission electron microscopy鈥揺nergy-dispersive X-ray spectroscopy, and scanning electron microscopy that MoVO crystals were grown from the cross-section of the rod-shaped crystals of the MoVO seeds.
