摘要

采用氩吸附等温线研究了氧化锰八面体分子筛OMS-1和OMS-2的微孔大小分布。利用圆柱形孔隙模型,该表征工具可为OMS-1提供准确的孔隙尺寸信息。然而,该方法在测量较小孔隙的OMS-2时精度较低。氩气吸附等温线测量可用于补充其他标准表征技术,以评估某些OMS产品的质量。

Micropore size distribution of octahedral molecular sieves (OMS)

Argon adsorption isotherms were used to study the micropore size distribution of manganese oxide octahedral molecular sieves, OMS-1 and OMS-2. Using the cylindrical pore model, this characterization tool provides accurate pore size information for OMS-1. However, this method is less accurate when measuring the smaller pore OMS-2. The argon adsorption isotherm measurement can be used to complement other standard characterization techniques to assess the quality of certain OMS products.
