摘要: Fe/MgO catalysts with large metallic particles were prepared by coprecipitation, and studied the help of Mossbauer spectroscopy magnetic techniques. Two activation processes H2 observed. At room temperature, was adsorbed on a small decrease in saturation magnetization, as previously reported literature. Above 470 K, hydrogen activated according reversible redox scheme Fen+ + nHadsFe nH+, n probably equal to 2. Protons are trapped basic sites catalyst giving OH groups.
