Heat capacity and thermodynamic functions of nano-TiO2 rutile in relation to bulk-TiO2 rutile

- Heat capacity data and thermodynamic properties for three TiO2 rutile nanoparticles of different hydration are presented.
- Water contributions were subtracted to yield thermodynamic properties of bare TiO2 rutile nanoparticles.
- These thermodynamic properties and those of bulk TiO2 rutile are equal within experimental error.
- Surface adsorbed water destabilizes the rutile phase in the nano-regime.
