Abstract
Low-pressure high-resolution hydrogen adsorption for the metal-organic framework MIL-101 are measured at 19.5 K and pressures below 57 kPa. The BET specific surface area and micropore volume are determined and compared to results from nitrogen adsorption at 77 K. Steps in the hydrogen adsorption isotherm are correlated to the pore structure of MIL-101.
摘要
在 19.5 K 和 57 kPa 以下的压力下测量了金属有机骨架 MIL-101 的低压高分辨率氢气吸附。测定了 BET 比表面积和微孔体积，并与 77 K 下氮气吸附的结果进行了比较。氢气吸附等温线的阶跃与 MIL-101 的孔结构相关联。
