Morphology-Controlled Flame Synthesis of Single, Branched, and Flower-like α-MoO3 Nanobelt Arrays

We report an atmospheric, catalyst-free rapid flame synthesis technique for growing single branched and flower-like alpha-MoO3 nanobelt arrays on diverse substrates. The growth rate, morphology, and surface coverage density of the alpha-MoO3 nanobelts were controlled, by varying, the flame. equivalence ratio, the source temperature, the growth substrate temperature, and the material and morphology of the growth substrate, This flame synthesis technique is a promising, alternative way to synthesize one-dimensional metal oxide nanostructures in general.
