Abstract

The process of magnetic-field-assisted preparation of ferromagnetic Ni–Co–Mn catalyst for deep oxidation/hydrogenation from a mixture of SHS-produced intermetallics was explored by SEM, XRD, and BET methods. Alkali leaching of precursor powder was carried out in the absence of magnetic field, in permanent magnetic field (240 mT), and in alternating magnetic field (27 mT, f = 50 Hz). The application of MF during the preparation of Ni–Co–Mn catalysts was found to affect (a) their specific surface and morphology and (b) catalytic activity/selectivity in deep oxidation of CO and propane and hydrogenation of СО2. The effect of MF was more pronounced in the process of hydrogenation and in case of alternating magnetic field.
