Vi. Bogillo et A. Voelkel, SURFACE-PROPERTIES OF RUTILE AND ITS MODIFIED FORM - PART 1 - SURFACECHARACTERISTICS STUDIED BY MEANS OF INVERSE GAS-CHROMATOGRAPHY, Journal of adhesion science and technology, 11(12), 1997, pp. 1513-1529
Molar adsorption free energies, adsorption enthalpies, and entropies o
f n-alkanes (C6-C10) and eight polar compounds possessing different do
nor-acceptor properties on the surface of titanium dioxide (rutile for
m) and TiO2, modified by sequential coating with amorphous Al2O3 (4% w
/w) and SiO2 (2% w/w) were measured by inverse gas chromatography. It
has been established that modification of the rutile surface leads to
an increase of the dispersive component of the surface free energy as
well as of the donor and acceptor characteristics of the solid and its
relative acidity.
