Probing the bimetallic RhCo_3 cluster preserved on SiO_2 after thermal treatment under O_2 by hydroformylation

摘要

RhCo_3(CO)_(12)/SiO_2, after decarbonylatioh under atmospheric O_2 at 623 K, exhibits excellent catalytic performances in atmospheric ethylene hydroformylation at 423 K, which is consistent with the corresponding catalysis by the bimetallic cluster catalyst RhCo_3/SiO_2.
