A novel and simple approach to induce solid-state oriented growth of molybdenum trioxide (MoO3) microparticles was explored, including the ball milling and thermal annealing processes. The obtained samples were characterised by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and ultraviolet–visible diffuse reflectance spectroscopy. It was found that the as-prepared samples were one-dimensional MoO3 microrods with high aspect ratios growing along the [001] orientation. In addition, as-prepared samples show better optical property. Moreover, a possible formation mechanism was also proposed, in which the surface diffusion played an important role in the inducing and growth processes.
