Iron’s abundance and low cost make it an attractive substitute for costly cobalt catalysts used for mediating Fischer-Tropsch (FT) synthesis. That industrial-scale carbon coupling process converts mixtures of CO and hydrogen to liquid fuels and other valuable organic products. But iron catalysts deactivate quickly during FT synthesis. The metal nanoparticles agglomerate, undergo phase changes, and accumulate a carbon buildup, all of which render iron catalysts inactive. Those problems can be avoided by preparing the catalyst . . .
