Growth of Molybdenum Oxide Nano-Micro Structures by Thermal Annealing Process

ORAL

Abstract

The needle and planar molybdenum oxide structures on molybdenum foil were grown by thermal annealing process. The effects of different parameters such as oxygen flow rate, presence of oxygen, annealing temperatures and annealing time on structures, grain size and aspect ratio of nano/micro structures were studied. It is found that the density of structures is only function of oxygen flow rate and annealing temperature. The maximum density of MoO3 nanorods were observed at annealing temperature 530$^{\circ}$C in air. The mechanism of the crystals growth was found for synthesized nanorods.
