感觉数据很奇怪，t-Method Micro Pore Volume.................................. 0.000E+00 cc/g？？ 为什么比表面积还很大啊？ 比表面积BET和Langmuir怎么差别这么大？ 有没有等温线的数据？ 孔容可以用这个： Total Pore Volume for pores with Diameter less than 5043.8 Å at P/Po = 0.99622........................ 6.043E-01 cc/g [ Last edited by willard on 2008-6-5 at 22:13 ] |

是做的一种介孔（mesoporous）材料吧，不像是活性炭。 Multipoint BET.............................................. 2.527E+02 m²/g t-Method External Surface Area.............................. 2.527E+02 m²/g t-Method Micro Pore Surface Area............................ 0.000E+00 m²/g BJH Interpolated Cumulative Adsorption Pore Volume for pores in the range of 5000.0 to 0.0 Å Diamater.................... 6.026E-01 cc/g BJH Interpolated Cumulative Desorption Pore Volume for pores in the range of 5000.0 to 0.0 Å Diamater.................... 6.200E-01 cc/g Average Pore Diameter....................................... 9.565E+01 Å 最好看图。 [ Last edited by dj_king on 2008-6-5 at 22:38 ] |
