The scanning hysteresis loop provides information about the correlation of the pore network, its connectivity and pore size distribution; nonetheless, this correlation cannot be revealed from the complete isotherm. To analyze the connectivity of the porous network in ordered mesoporous materials modified with iron and cobalt oxides, Ar adsorption–desorption isotherms and their corresponding scanning of the hysteresis loops at three temperatures (65, 77, and 87 K) were measured. Two mathematical models based on the independent domains theory (i.e. Uncorrelated Model (UM) and Partial Correlated Model (PCM)) were applied to adjust the desorption branches in the hysteresis loops associating these results to the connectivity in the porous network and the presence of pore-blocking effects.

扫描磁滞回线提供有关孔隙网络、连通性和孔径分布的相关性信息；尽管如此，这种相关性无法从完整的等温线中揭示出来。为了分析用铁和钴氧化物改性的有序介孔材料中多孔网络的连通性，测量了 Ar 吸附-解吸等温线及其在三个温度（65、77 和 87 K）下相应的滞后回线扫描。应用基于独立域理论的两个数学模型（即不相关模型 (UM) 和偏相关模型 (PCM)）来调整滞后回线中的解吸分支，将这些结果与多孔网络中的连通性和孔隙的存在相关联-阻挡效果。
