ABSTRACT: The effect of dispersivity on thermodynamic and kinetic parameters
of chemical reactions in nanodispersed systems is theoretically investigated.
On the basis of the established theoretical dependences the new method of
determination of surface thermodynamic properties of nanoparticles (surface
enthalpy, surface entropy and surface energy) by thermal analysis (DTA or DSC)
was developed. Three examples of calculation of surface properties of
nanoparticles were presented to prove the feasibility of this method.
