Synthesis of nanosize Co-Rh systems and study of their properties

Abstract

Precursor compounds [Co(NH3)6][Rh(NO2)6] and [Co(NH3)6][Co(NO2)6], solid solutions [Co(NH3)6] [Rh(NO2)6]1−x[Co(NO2)6]x, and solid solutions Na3[Rh1−xCox(NO2)6] were synthesized and studied by IR spectroscopy and elemental, X-ray phase, X-ray diffraction, and thermogravimetric analyses. X-ray phase analysis was employed to examine products of thermal decomposition of precursors in the atmospheres of hydrogen and helium. Catalysts with a Co-Rh active system, supported by ZrO2, were prepared and tested in the reaction of steam conversion of ethanol.
