Low-temperature synthesis of morphology controlled metastable hexagonal molybdenum trioxide (MoO3)

We demonstrate a simple low-temperature chemical method to produce metastable hexagonal MoO3 phase nanorods. The structure, chemical purity, thermal stability and optical properties of hexagonal MoO3 are reported. Our results provide a more direct method to produce high quality and stable hexagonal MoO3, which exhibits phase stability up to 400 ∘C at which point an irreversible phase transition occurs to form orthorhombic MoO3.
