Platinum Group Metal Phosphides as Heterogeneous Catalysts for the Gas-Phase Hydroformylation of Small Olefins
No full textA method
for the synthesis of highly crystalline Rh<sub>2</sub>P nanoparticles
on SiO<sub>2</sub> support materials and their use
as truly heterogeneous single-site catalysts for the hydroformylation
of ethylene and propylene is presented. The supported Rh<sub>2</sub>P nanoparticles were investigated by transmission electron microscopy
and by infrared analysis of adsorbed CO. The influence of feed gas
composition and reaction temperature on the activity and selectivity
in the hydroformylation reaction was evaluated by using high throughput
experimentation as an enabling element; core findings were that beneficial
effects on the selectivity were observed at high CO partial pressures
and after addition of water to the feed gas. The analytical and performance
data of the materials gave evidence that high temperature reduction
leading to highly crystalline Rh<sub>2</sub>P nanoparticles is key
to achieving active, selective, and long-term stable catalysts
