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 相對于利用中孔sio _ 2為模板合成的中孔碳材料,我們的合成方法更簡單直接,并且如此大孔徑的有序中孔碳材料也是首次報(bào)道。
