Title: Sulfurization of α-MoO{sub 3} nanostructured thin film

In this report, the sulfurization of vertically aligned molybdenum trioxide (α- MoO{sub 3}) nanoflakes (NFs) with high aspect ratio (height/thickness >20) on the nickel coated glass substrates in a mixture of H{sub 2}S and argon gas at atmospheric pressure has been studied. The effect of sulfurization have been investigated to understand the basic reaction mechanism and the morphology, structural properties of grown nanoflakes. XPS and XRD indicate the formation of MoS{sub 2} along with the other intermediate phase such as MoO{sub 2} at temperature 200 °C. The surface morphology of samples have been studied systematically by using scanning electron microscope (SEM). The results demonstrate partial conversion of MoO{sub 3} NFs into MoS{sub 2} along with the change in the morphology of nanoflakes. All the observed results are well in consonance with each other.
