To expand our knowledge of nanoparticle adsorption thermodynamics
we must conduct theoretical and experimental research.
Here, the thermodynamic theory of nanoadsorption was extended.
By studying the adsorption of Cu2+ on ZnO nanoparticles of different
sizes and the adsorption of Ag+ on TiO2 nanoparticles of different
sizes, the effects of size on the equilibrium constant, the molar
Gibbs free energy, the molar enthalpy and the molar entropy of
adsorption were investigated.
