Structural and acidity characterization of TiO2-Nb2O5 based nanomaterials (mixed oxides and core@shell) and their evaluation under the acetone hydrodeoxygenation reaction

These materials were characterized using: (1) X-ray scattering techniques to probe structural properties, including X-ray diffraction (XRD) and pair distribution function (PDF) analysis; (2) the adsorption of probe molecules to evaluate their acidity, including nuclear magnetic resonance (NMR) of phosphorus isotope (31P) of adsorbed trimethylphosphine oxide (TMPO), Fourier transform infrared spectroscopy (FTIR) of adsorbed pyridine (Py), and temperature programmed desorption (TPD) of ammonia (NH3).

Here, we also include the data regarding the catalytic evaluation of metal-supported catalysts using the TiO2-Nb2O5 materials as support in the acetone hydrodeoxygenation (HDO) reaction.
