Abstract

Different loadings of Fe-incorporated MCM-41 (∼ 1, 2, and 3 wt %) were hydrothermally synthesized using different colloidal silica (HiSil-915 and Cab-O-Sil) and C16 surfactant. These materials were then used as catalytic templates for the production of carbon nanotubes by acetylene pyrolysis at 1 atm. High carbon yields were observed for catalysts containing ∼ 1 and 2 wt % Fe while catalysts with ∼ 3 wt % Fe showed relatively lower activity for carbon formation. Catalysts synthesized from Cab-O-Sil were more stable and maintained their high mesoporous structural quality better than those synthesized from HiSil-915, which is of lower purity than Cab-O-Sil. This is an abstract of a paper presented at the AIChE Annual Meeting (Austin, TX 11/7-12/2004).
