PKU Researchers Carry Out Aqueous Fischer-Tropsch Reaction for First Time
12 December 2007
Chemistry World. Researchers at Peking University (PKU) in China have carried out the Fischer-Tropsch (FT) reaction in water for the first time.
Instead of using the classic approach of a metal catalyst (usually iron or cobalt) supported on carbon or silicon dioxide, the PKU team catalyzed the reaction in water using 2nm clusters of ruthenium, stabilized by PVP, a water-soluble polymer.
The unsupported catalyst is more active than conventional catalysts and so the reaction runs well at lower temperatures. The researchers saw a 35-fold increase in activity over supported catalysts at a standard operating temperature of 150°C, and a 16-fold increase at only 100°C.
Because the resulting hydrocarbons don’t mix with water, the product is uncontaminated by the catalyst.

"2nm clusters of ruthenium"
Damn! Why didn't I think of that. >_<
