A collaborative research between Delft and Utrecht University led to the development of a stepwise methodology that, making use of a cobalt-containing metal organic framework as hard template (ZIF-67), allows Independently controlling metal loading, nanoparticle size, distribution, and accessibility this long-standing challenge. Condensation of silica in the Co-metal organic framework pore space followed by pyrolysis and subsequent calcination of these composites renders highly loaded cobalt nanocomposites (~ 50 wt.% Co), with cobalt oxide reducibility in the order of 80% and a good particle dispersion, that exhibit high activity, C5 + selectivity and stability in Fischer–Tropsch synthesis.
