    2002-3-25 · It was observed that alumina–silica systems containing 20 wt.% of Al showed very high activity towards MWNTs formation. One important point to be considered while selecting a support for a metal when preparing a catalyst is probably that it should not only result in a high density of NTs, but also be separated easily from the carbon deposit by a suitable and simple method to obtain pure NTs.
