The metal molybdenum occurs in various oxidation states in nature and is used as a major industrial raw material. The most commonly used form is the molybdenum(IV) oxide (MoO2) which is obtained by roasting MoO2 disulfide, a major molybdenum ore. Although oxide compounds generally are not conductive to electricity, perovskite structured oxides such as molybdenum(IV) oxide exhibit electrical conductivity similar to that of metals and find applications in many areas including photocatalysis and solid-oxide fuel cells (SOFC).
Single valency oxides of vanadium and molybdenum have fascinating structures which have large deviations from Pauling’s electrostatic valence bond theory as their building units consist of distorted octahedra linked by comers or/and edges. The richness of these arrangements makes it difficult to predict their microscopic behavior and surface properties.
In this paper we report the effects of biofield energy treatment on mesoporous alumina-supported molybdenum(IV) oxide. The catalysts were prepared by spraying a solution of ammonium heptamolybdate on mesoporous alumina and then calcining it in air. After the biofield energy treatment, the BET surface area and catalytic activity of the molybdenum(IV)oxides were investigated by X-ray diffraction and FT-IR spectroscopy.
The X-ray diffraction results show that the crystal structure of the molybdenum(IV)oxides after the biofield energy treatment has an inverse perovskite structure as indicated by the polarization rotation of the Mo-O bond. The FT-IR spectra revealed that the vibration frequency of the symmetric Mo-O bond was reduced after the treatment. The absorption band observed at 466 cm-1 in the control sample was shifted to lower wavenumber 450 cm-1in the treated molybdenum(IV)oxide suggesting that bond strength has been reduced.
