摘要：

Samples of composite nanomaterials obtained by the thermal treatment of mixtures of MoO3 nano-dispersed powder and ultrafine powder of Mo with precipitate from removing iron from groundwater are studied by means of X-ray diffraction and infrared spectroscopy. The structure of these samples (phase composition, average crystallite size, microdistortions (microstresses) of their crystal lattices, and certain texture parameters) are determined. It is suggested that under certain conditions, shells from the nanoparticles of Mo and/or MoO3 are formed on the surface of sediment particles, preventing the identification of iron-containing phases. Estimates are made of the sorption activity of some materials with respect to carbon monoxide (CO).
