摘要：

The adsorption of N2, H2O, CH3OH, CCl4, C6H6, and C6H5Cl on microporous hematite with well-defined slit-shaped pores of a width of 0.8 nm has been measured at relative equilibrium pressure from 10(-5) to ca. 0.7. The difference among the initial slopes of the isotherms of these adsorbates can be interpreted based on the adsorption potential in the slit-shaped micropore, the molecular size and polarity of the adsorbates, and the chemisorption. The results of in situ FTIR indicated that the surface Fe-OH groups function as adsorption sites.
