以含模板剂的中孔MCM-41为模板合成类碳纳米管材料

A carbon nanotube analog was prepared using the structuredirecting agent cetyltrimetylammonium bromide locked in the channels of MCM41 as a carbon source. The structures and properties of the resulting samples were characterized by powder XRD, nitrogen adsorptiondesorption measurement, TEM and TGA. It was found that the carbon nanotube analog obtained by this method is amorphous. Pretreatment with concentrated sulfuric acid is a key step in its formation.
