Abstract

MCM-41 and SBA-15 mesoporous silicates of various pore diameters were synthesized using the conventional micelle-templated synthesis and micelle swelling methods [1,2,3]. The samples containing organic template agents were characterized by 13C and 29Si MAS NMR spectroscopy. Carbonisation of the template molecules was performed at 800 °C for 30 min under helium in sealed quartz tubes. This particular heat treatment generally leads to the formation of carbon nanotubes inside the channels of the mesoporous silicates. The dissolution of silica by HF solution results in well-separated carbon nanotubes as well as various forms of carbon observed by transmission electron microscopy (TEM).
