In summary, the adsorption capacity of HMOR and NaMOR with
low surface area depended on its channel size, and the HY5.6,
HY4.8, HY901, and MS13X with relatively large surface area depended
on the volume of the mesopores. HY901 revealed the most
remarkable hysteresis phenomena among the used zeolites, implying
that it possessed many ink-bottle shaped mesopores.
