Effect of the porosity and relative surface hydrophobicity of MCM-41 materials on the adsorption of [60]fullerene at the solid/toluene interface: comparison of Al- and Zr-doped silicates with the purely siliceous sample

Abstract

The adsorption of [60]fullerene from toluene on three MCM-41 type materials: purely siliceous, aluminosilicate and zirconiosilicate, is thought to occur primarily on the pore walls, and differences in the amount adsorbed between the three samples can be ascribed to the different size, volume and surface area of their pores rather than to the different hydrophobic character of their surfaces.
