Bimetallic FeCo Nanocrystals Supported on Highly Porous Silica Aerogels as Fischer–Tropsch Catalysts

In this work, nanocomposites constituted of FeCo alloy nanoparticles dispersed on a highly porous silica aerogel have been designed as catalysts for low temperature Fischer-Tropsch synthesis. The catalysts were characterized by XRD, TEM, N 2 physisorption and SEM analysis. A high catalytic activity with CO conversions up to 95 % has been obtained, with enhanced selectivity for the C 2-C 4 hydrocarbons.
