Temperature Effect on the Surface Properties of ZnO(am)
The point of zero charge and surface acidity constants of zinc oxide were determined over the temperature range 293–323 K. Both the point of zero charge (pzc) and the surface acidity constants (pK a1 and pK a2 ) were found to decrease with increasing temperature. The values of the dissociation const...

| description | The point of zero charge and surface acidity constants of zinc oxide were determined over the temperature range 293–323 K. Both the point of zero charge (pzc) and the surface acidity constants (pK a1 and pK a2 ) were found to decrease with increasing temperature. The values of the dissociation constants (pK a1 and pK a2 ) determined from the Henderson-Hasselbach equation agreed very well with those determined using the Gaines-Thomas equation. The thermodynamic parameters ΔH 0 and ΔS 0 for the processes were also evaluated. |
