Breaking the dispersion-reducibility dependence in oxide-supported cobalt nanoparticles
Cobalt metal nanoparticles ca. 4-5 nm in size synthesized in the core of reverse n-ficelles and supported on surface-protected delaminated ITQ-2 zeolite display a very narrow particle size distribution and a high reducibility typical of larger particles. The methodological preparation approach presented here allows breaking of the dispersion-reducibility dependence inherent to very small cobalt particles supported on oxidic carriers, thereby overcoming long-lasting difficulties in studying particle size effects in highly dispersed cobalt-based Fischer-Tropsch catalysts.
