A vacuum heating operation at 623 K on the surfaces of SiO_2-supported promoted ca- talysts makes it possible to reveal the electron transfer from Co and Fe additives to Rh atoms: 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 chemisorp- tions on Rh in connection with their promotion in the selective hydroformylation of propy- lene. 展开更多
