Abstract

We have recently reported a solid-state, mass-quantity transformation from V₂O₅ powders to nanorods via a two-step approach [1]. In this paper we present detailed investigation of the growth process using x-ray diffraction, scanning/transmission electron microscopy and electron spin resonance. The growth of nanorods at intermediate stages has been examined. Oxidation, surface energy minimization and surface diffusion play important roles in the growth mechanism.
