Exact characterization of micro- and mesopore surface areas and pore volumes of micro-/mesoporous catalysts can be achieved by corrections of t-plot analysis performed from nitrogen adsorption isotherms at 77 K. Until now, these corrections were restricted to mesoporous FAU-Y zeolites. By analyzing mixtures of purely mesoporous materials as MCM-41 and zeolites, these corrections are now available for hierarchical MFI, *BEA, and MOR zeolites.

通过校正 t 曲线分析测定中孔沸石的微孔和中孔表面积和体积

通过对 77 K 下的氮吸附等温线进行的 t 图分析的校正，可以实现对微孔和中孔表面积和微孔/中孔催化剂的孔体积的精确表征。到目前为止，这些校正仅限于中孔 FAU-Y 沸石. 通过分析纯介孔材料（如 MCM-41 和沸石）的混合物，这些校正现在可用于分级 MFI、*BEA 和 MOR 沸石。
