A more accurate estimation of the specific surface area of TiO<sub>2</sub> nanoparticles capped with organic ligands
The specific surface area is important information for nanoparticles. Herein, we demonstrate that treatment with F<sup>-</sup> ions can strip organic ligands from the surface of TiO<sub>2</sub> nanoparticles, which enables a more accurate estimation of the specific surface area using N<sub>2</sub> adsorption-desorption isotherms in conjunction with the Brunauer-Emmett-Teller model.
