Conclusions

  1. 1.

    Temperature intervals and kinetic parameters have been established for the evolution, from TiO2, of n-butylamine molecules forming surface hydrogen and coordination bonds with the adsorption centers; also, the temperature interval and kinetic parameters have been established for processes of thermolysis of surface amino compounds with a Ti-N σ-bond.

  2. 2.

    The character of adsorptive interaction of n-butylamine with TiO2 does not depend on the degree of hydroxylation of the surface.

  3. 3.

    When the amine-modified surface of rutile is exposed to light at −20°C, significant quantities of products of n-butylamine oxidation and autocondensation are formed. A decrease in the degree of hydroxylation of the TiO2 surface increases the photochemical stability of the adsorption system.
