Sk. Ihm et al., CHARACTERISTICS OF METALLIC IRON IN Y-ZEOLITE CATALYSTS REDUCED BY HYDROGEN-ATOM BEAMS, Reaction kinetics and catalysis letters, 57(2), 1996, pp. 301-309
Hydrogen atom beams were used to reduce the ionic species of iron-Fe(I
I) and Fe(III) in Y-zeolite. Reduction to metallic states was confirme
d by ferromagnetic resonance (FMR) spectroscopy, and the catalytic act
ivity in CO hydrogenation showed high selectivity towards ethylene and
butene.
