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-DOPED AND ZR-DOPED SILICATES WITH THE PURELY SILICEOUS SAMPLE/

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