t-method 计算没有微孔， 而DR,HK, SF都计算出微孔，应该用哪个？在小木虫看到t-method, DR,HK, SF都是分析微孔的方法，他们有什么区别和特别的应用吗？ BJH Method Cumulative Adsorption Pore Volume 怎么会比总的孔容 Total Pore Volume for pores 还大？ 以前没做过这方面分析，请专家帮忙分析一下？ SURFACE AREA DATA Multipoint BET.............................................. 9.974E+01 m²/g Single Point BET............................................ 8.701E+01 m²/g Langmuir Surface Area....................................... 1.817E+02 m²/g BJH Method Cumulative Adsorption Surface Area............... 1.991E+02 m²/g BJH Method Cumulative Desorption Surface Area............... 8.357E+01 m²/g DH Method Cumulative Adsorption Surface Area................ 2.079E+02 m²/g DH Method Cumulative Desorption Surface Area................ 8.732E+01 m²/g t-Method External Surface Area.............................. 9.974E+01 m²/g t-Method Micro Pore Surface Area............................ 0.000E+00 m²/g DR Method Micro Pore Area................................... 1.523E+02 m²/g PORE VOLUME DATA Total Pore Volume for pores with Diameter less than 7881.2 Å at P/Po = 0.99757........................ 1.072E-01 cc/g BJH Method Cumulative Adsorption Pore Volume................ 1.450E-01 cc/g BJH Method Cumulative Desorption Pore Volume................ 7.384E-02 cc/g DH Method Cumulative Adsorption Pore Volume................. 1.439E-01 cc/g DH Method Cumulative Desorption Pore Volume................. 7.338E-02 cc/g t-Method Micro Pore Volume.................................. 0.000E+00 cc/g DR Method Micro Pore Volume................................. 5.412E-02 cc/g HK Method Cumulative Pore Volume............................ 3.255E-02 cc/g SF Method Cumulative Pore Volume............................ 3.395E-02 cc/g PORE SIZE DATA Average Pore Diameter....................................... 4.300E+01 Å BJH Method Adsorption Pore Diameter (Mode).................. 1.380E+01 Å BJH Method Desorption Pore Diameter (Mode).................. 1.946E+01 Å DH Method Adsorption Pore Diameter (Mode).................. 1.380E+01 Å DH Method Desorption Pore Diameter (Mode).................. 1.946E+01 Å DR Method Micro Pore Width .............................. 1.813E+02 Å DA Method Pore Diameter (Mode)............................. 1.880E+01 Å HK Method Pore Width (Mode)............................. 1.362E+01 Å SF Method Pore Diameter (Mode)............................. 2.547E+01 Å 本帖关键词：Adsorption Pore BET Volume Method |
