Publikováno v: ChemInform. 25
Silica supported ruthenium catalysts have been prepared by incipient wetness impregnation with RuCl3 (aq). After drying and reduction these catalysts were additionally treated with carbon monoxide or CO/H2 at 250°C. Due to this treatment the catalys

An E.S.R. study of the reaction of cobalt phthalocyanines with ammonia and dioxygen
Autor: J. Zwart, J. H. M. C. Van Wolput
Publikováno v: Journal of Molecular Catalysis. 5:51-64
The interaction of cobalt phthalocyanine with ammonia and oxygen in solutions of DMF was studied and the products investigated by e.s.r. Both mono- and bis-NH 3 adducts were prepared and characterized by their e.s.r. signals showing the appropriate 1
