Uittreksel

Ordered mesoporous materials, MCM-41, with varying Si/Al ratios have been synthesised and characterised by adsorption, XRD, NMR, and FTIR measurements. 27Al MAS NMR shows four-fold co-ordination of Al incorporated into the structure. The combined study by microcalorimetry and FTIR, using acetonitrile as probe shows a few strong Lewis sites and only weak Brønsted acidity. The physisorption properties were analysed by N2, n-hexane, benzene, acetonitrile, methanol and water adsorption using microcalorimetry and isotherm measurements. MCM-41 shows adsorption behaviour of a well-defined mesoporous molecular sieve. The heat of adsorption of a non-polar molecule is mainly determined by the pore diameter of the porous material. A characteristic feature of all applied adsorptives is capillary condensation. Whereas isotherms of water are completely irreversible and acetonitrile shows a small hysteresis, isotherms of the non-polar benzene, n-hexane, and nitrogen are completely reversible.
