“…Protonated titanate nanotube (PTNT) was proved to be an effective solid acid catalyst for the hydroxyalkylation/alkylation (HAA) of 2-methyfuran (2-MF) and n-butanal from lignocellulose [399]. Compared with some often used inorganic solid acid catalysts, the PTNT has higher activity for the HAA of 2-MF with n-butanol.…”

Titanates are salts of polytitanic acid that can be synthesized as nanostructures in a great variety concerning crystallinity, morphology, size, metal content and surface chemistry.Titanate nanotubes (open-ended hollow cylinders measuring up to 200 nm in length and 15 nm in outer diameter) and nanowires (solid, elongated rectangular blocks with length up to 1500 nm and 30-60 nm diameter) are the most widespread representatives of the titanate nanomaterial family. This review covers the properties and applications of these two materials from the surface science point of view. Dielectric, vibrational, electron and X-ray spectroscopic results are comprehensively discussed first, then surface modification methods including covalent functionalization, ion exchange and metal loading are covered. The versatile surface chemistry of onedimensional titanates renders them excellent candidates for heterogeneous catalytic, photocatalytic, photovoltaic and energy storage applications, therefore, these fields are also reviewed.

“…The two broad bands at 1540 and 1635 cm −1 were only observed on TNT-H. The appearance of these bands is resulted from the protonation of pyridine into pyridinium ions indicating the availability of Brønsted acid sites [22][23][24]. From this result, we can see that the proton-exchange of TNT leads to the indicating that FA hardly adsorbs on the anatase.…”

“…4. As can be seen, the three solids presented signals located between 1445 cm -1 and 1605 cm -1 , which have been related to Lewis acid sites [23,24]. In this sense, the modification with fluoride ions does not modify the type of acidity of TiO2.…”

This study evaluated the synthesis, characterization, and activity of fluorinated titanium dioxide materials (TiO2-F 1% and TiO2-F 5%) in-situ modified by the sol-gel method in the esterification reaction of levulinic acid conducted by catalytic and photocatalytic processes. The physicochemical properties of the materials were determined by X-ray diffraction, UV–Vis diffuse reflectance spectroscopy, thermal analysis, and pyridine adsorption. It was found that the inclusion of fluoride anion causes a decrease in the levulinic acid conversion by photocatalytic reaction; however, in the catalytic activation, a slight increase in the conversion using the fluoride materials was observed. Finally, the reaction in the presence of halogenated solvents (CCl4) by photolysis reaction favors a conversion of 100% in 1h.
