Resumo
Transition metal structures (such as cobalt, nickel, and molybdenium) have been the subject
of studies in recent years due to their electrical, catalytic and magnetic properties.
Orthorhombic molybdenum trioxide (α-MoO3) is relevant because it is an antioxidant
material, leading to its catalytic properties that are influenced by the valence state of
molybdenum ions and the local environment where they are inserted. These structures have
been investigated in developments of sensors, energy storage and the formulation of gels for
the treatment of chronic diseases [1]. In this perspective, the present work proposes the use
of the molybdenum (II) acetate as a metallic precursor for obtaining α-MoO3 structures by
the thermal decomposition method [2]. The Mo (II) acetate belongs to a group of metal
complexes composed of two highly correlated Mo ions, in which each cations are connected
to complexes containing oxygen. This reagent could favor, in specific chemical route, the
crystallization of MoxOy [2][3]. The syntheses yields were characterized by X-ray diffraction
(XDR), scanning electron microscopy (SEM), and energy-dispersive analysis (EDS). The X-ray
diffraction results suggested α-MoO3 crystallite of the 77 nm (by the Scherrer equation).
By means of microscopy analysis were observed that the obtained morphology is microrod-like,
with a of approximately 774 nm and a length of the 37 micrometers. The EDS analysis
only showed energies related to molybdenum (Mo) and oxygen (O), confirming the purity of
the obtained material.
