ELECTROH-DONATING BEHAVIOR OF Co AND Fe IH PROMOTED Rh CATALYSTS
摘要:
A vacuum heating operation at 623 K on the surfaces of SiO2-supported promoted ca-talysts makes it possible to reveal the electron transfer from Co and Fe additives to Rhatoms:a Rh catalyst containing 1% Eh under CO exhibits geminal CO IR bands only, while the presence of Co and Fe in promoted Rh catalysts results in linear and bridged CO chemisorptions on Rh in connection with their promotion in the selective hydroformylation of propylene.
