Abstract
The specific surface area is important information for nanoparticles. Herein, we demonstrate that treatment with F− ions can strip organic ligands from the surface of TiO2 nanoparticles, which enables a more accurate estimation of the specific surface area using N2 adsorption–desorption isotherms in conjunction with the Brunauer–Emmett–Teller model.
