Composición catalítica para la síntesis de nanotubos de carbono
Catalyst composition comprises a mixture of iron and cobalt in any form of oxidation and catalyst support comprising exfoliated vermiculite. Independent claims are included for: (1) synthesizing the catalyst composition, comprising exfoliating the vermiculite by treating vermiculite ore at above 800[deg] C, contacting the exfoliated vermiculite with a solution of a salt of cobalt and iron, and calcining the contacted vermiculite at above 350[deg] C; and (2) synthesizing carbon nanotubes by decomposition of hydrocarbon gas on the catalyst composition, comprising conditioning the catalyst composition in an inert atmosphere, and contacting the catalyst composition with a source of carbon gas at 600-800[deg] C for at least 5 minutes.
