基于Brumauer-Emmett-Teller(BET)方法,采用高精度比表面积和孔径测定仪在 77 K 下的氮气吸脱附等温线,测量样品
的比表面积。
Based on the Brumauer-Emmett-Teller (BET) method, the specific surface area of the sample was measured by nitrogen adsorption and desorption isotherm at 77 K with a high precision specific surface area and aperture analyzer.
