ABSTRACT:

A general procedure for the synthesis of some new, effective heterogeneous catalysts containing highly dispersed transition metal compounds on supports has been developed. The initial work involved alumina as the support material although recently the procedure has been applied to the synthesis of materials containing simple and complex oxides as supports. This procedure is different from that used previously by researchers attempting to prepare catalytic materials containing supported metal compounds. The potential catalysts were synthesized from solutions of the carbonyls Ru sub 3 (CO) sub 12 , Ir sub 4 (CO) sub 12 , Rh sub 6 (CO) sub 16 , Os sub 3 (CO) sub 12 , Fe sub 3 (CO) sub 12 , Co sub 4 (CO) sub 12 and the supports either as powders, or as 1/8'' extrudates or pellets in the case of alumina, by a carefully designed and controlled  procedure. The procedure may be conducted in the presence of air or an inert gas such as dry N sub 2 ; usually a dried, de-gassed non-polar solvent is employed as the medium. The developed procedures are similar for the synthesis of each potential catalyst, however the solvent and reaction times employed may vary with the carbonyl and support used. Total metal concentration has been determined by x-ray fluorescence or atomic absorption spectroscopy and varies between 1 and approximately 20%. The synthesized materials may be handled in air; evidence from optical and scanning electron microscope studies,. (ERA citation 07:059114)
