## Abstract BET, scanning electron microscopy, X‐ray diffraction, Mössbauer spectroscopy, X‐ray fluorescence spectroscopy and McBain thermobalance were used to investigate the effect of cobalt on the reduction behavior and activity of used iron catalyst for ammonia synthesis. Activity tests were ca

The oxidized form of a model, fused iron catalyst for ammonia synthesis, containing large amounts of wustite (ca. 40 wt.-%), was activated by reduction. The reduction of catalyst samples with different thermal history and different grain size was continuously monitored by thermogravimetry as well as
## Abstract Summary: A new procedure was developed to support [(ArNC(Me))~2~C~5~H~3~N]FeCl~2~ (Ar2,4,6‐trimethylphenyl) on spherical MgCl~2~ for ethylene polymerization. The resultant catalysts showed ten times higher activity of the corresponding catalyst in homogeneous catalysis. The morphologi
