Monometallic and bimetallic catalysts consisting of Rh/MCM-41 and RhM3/MCM-41 (M = Fe, Co, Ni, Cu, or Zn) were synthesized and tested for vapor-phase ethylene hydroformylation reaction. Co showed a significant promotion effect on the selectivity of hydroformylation to C-3 oxygenates, followed by Fe and Cu, while Ni and Zn had a negative effect. Density functional theory (DFT) calculations revealed that the addition of a secondary metal can create a new type of site, allowing for selective tuning of the binding energies of reaction intermediates, thereby leading to different catalytic performances.
Monometallic Rh/MCM-41 and bimetallic RhM3/MCM-41 (M = Fe, Co, Ni, Cu, or Zn) catalysts are synthesized and tested for vapor-phase ethylene hydroformylation reaction. Co is found to exhibit a significant promotion effect on the selectivity of hydroformylation to C-3 oxygenates, followed by Fe and Cu, with Ni and Zn showing a negative effect. DFT calculations reveal that the addition of a secondary metal can provide a new type of site, being able to selectively tune the binding energies of reaction intermediates, and thus lead to different catalytic performances.
