Electrosynthesis of molybdenum oxide thin films onto stainless substrates

Abstract

The electrodeposition of uniform, nanocrystalline and highly oriented molybdenum oxide thin films was investigated at room temperature onto stainless steel Substrates using citric acid as a complexing agent. The electrodeposition process of molybdenum oxide thin films from molybdic acid of various concentrations onto stainless steel substrate were studied by utilizing the electrochemical techniques. The prepared films were characterized for their structural, surface morphological and compositional properties by means of X-ray diffraction, scanning electron microscopy, transmission electron microscopy and energy dispersive X-ray analysis. X-ray diffraction and transmission electron microscopy experiment reveals that the films are of crystallized size. XRD experiment showed that the crystallized product is composed of molybdenum oxide with dominant orientations of MoO3. (c) 2005 Elsevier B.V. All rights reserved.
