With the specific goal of preparing a Fischer-Tropsch (FTS) catalyst, we developed a new method that gives supported spherical core-shell materials with an iron core and a cobalt shell and ensures their core-shell structure is retained upon activation. The synthesis method is cheap and scalable to the multi-ton scale required. The materials proved to be efficient FTS catalysts. An efficient particle design suggests confining the active, more expensive phase on a thin shell grown on a cheaper core of the proper size. Herein we have reported a new approach to address the efficient preparation of size-dependent performance catalysts.
