Abstract

original image

Not just for anglers: An unprecedented oxygenate selectivity of 70 % in the Fischer–Tropsch synthesis is achieved by using a Ru nanoparticle catalyst in the aqueous phase. A kinetic analysis of the anomalous temperature dependence of the chain growth probability shows that hydrocarbons and oxygenates are formed on different sites. Oxygenates (hydrocarbons) form on sites with high (low) barrier for CO dissociation.
