Abstract

<jats:p>MoO<jats:sub>3</jats:sub> nanostructures with tunable phases such as <jats:italic>α</jats:italic>-MoO<jats:sub>3</jats:sub>, <jats:italic>β</jats:italic>-MoO<jats:sub>3</jats:sub> and their mixed phases were synthesized via a simple solid state decomposition method and employed as electrocatalyst for the detection of biomolecule. The phaseand crystal structure of the synthesized MoO<jats:sub>3</jats:sub> nanostructures were confirmed through X-ray diffraction (XRD) studies. The MoO<jats:sub>3</jats:sub> nanostructures were also characterized by Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, X-ray photoelectron spectroscopy(XPS), and UV-Vis spectroscopy for their structural, chemical state and optical properties, respectively. The observed results confirmed the successful formation of phase tunable MoO<jats:sub>3</jats:sub> nanostructures. The surface texture and morphology of the samples was characterized by field emissionscanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM). The obtained images showed the formation of hexagons, cubes and rods morphology of MoO<jats:sub>3</jats:sub>. The synthesized MoO<jats:sub>3</jats:sub> nanostructures were used to modify the surface of glassy carbon electrode (GCE)to detect biomolecule (quercetin).</jats:p>
