Cobalt is relative expensive than iron

Cobalt is relative expensive than iron. However, to reduce the cost of the catalyst, the cobalt metal is often dispersed onto a support, which should be inert in nature, thermally and mechanically stable, possess balanced metal-support interaction, as well as have a surface area that is solvent-accessible. The implication is that the dispersed metal should not form a metal alloy with the support. Often, Co catalysts are supported by metal compounds such as TiO₂, AL₂O₃, and SiO₂. In spite of these, silica nanosprings (NS) has been cited to go past the criteria employed in the case of TiO₂, AL₂O₃, or even SiO₂. According to recent research to compare the catalytic performance of Fischer-Tropsch, it was evident that there was high Fischer-Tropsch Synthesis activity whenever CO/NS was used, as opposed to the case of silica gel catalysts (Pintar 2000). Often, the conversion rates of CO are influenced by a number of factors such as the failure of Co specie to be completely reduced, sintering and coking of the nanoparticles of CO.
