These amorphous carbon tubes are totally different from those graphitized carbon nanotubes obtained through traditional methods . the simple and direct synthesis method is superior to the usual casting method by mesoporous silica materials 相对于利用中孔sio _ 2为模板合成的中孔碳材料，我们的合成方法更简单直接，并且如此大孔径的有序中孔碳材料也是首次报道。
