Based on data obtained by X-ray diffraction and Mössbauer spectroscopy, it was concluded that tetragonal distortions appeared in the structure of cubic TiFe upon doping with Zr and Mo atoms and the intermetallide TiFe0.95Zr0.03Mo0.02 is formed, which can absorb ∼1 mol of H2 per mole of the intermetallide. The heating of the hydrogen-saturated intermetallide in Ar to 185°C released ∼0.80–0.82 mol of...
Catalytic properties and structural aspects of the formation of iron–cobalt–chromium catalysts depending on the temperature of preliminary treatment are studied. A catalytically active iron–cobalt–chromium spinel is formed at a calcination temperature of 580–600°C. If catalytic packings are overheated in the course of hydrocarbon fuel oxidation or if temperatures above 700°C are used for preliminary...
