催化剂的孔分布问题
|
||
|
前几天测了载体的比表面积和孔径，孔体积。这些数据都有，请问能不能看出孔的分布情况？也就是不同粒度所占的含量？老师测的，现在想知道孔的分布趋势。我是看不出来，如下图 请高手帮忙解图 Langmuir Surface Area Report Langmuir Surface Area: 453.9472 ? 9.0294 m?g Slope: 0.009590 ? 0.000191 Y-Intercept: 0.000321 ? 0.000026 b: 0.033474 VM: 104.278989 cm?g STP Correlation Coefficient: 9.988152e-01 Molecular Cross-section: 0.1620 nm?
