Laser Desorption/Ionization Mass Spectrometry as a Potential Tool for Evaluation of Hydroxylation Degree of Various Types of Titanium Dioxide Materials

For many applications, TiO2 must have a unique surface structure responsible for its desirable physicochemical properties. Therefore the fast and easy methods of TiO2 surface characterization are of great interest. Heated TiO2 samp...
