Hydrogenated mesoporous TiO2–SiO2 with increased moderate strong Brönsted acidic sites for Friedel–Crafts alkylation reaction

Author affiliations

Abstract

The acidic properties of mesoporous TiO2–SiO2 mixed oxides were evaluated by 31P magic-angle spinning NMR spectroscopy using trimethylphosphine oxide (TMPO) and trimethylphosphine (TMP) as probe molecules. It confirms that mesoporous TiO2–SiO2 has moderate strong Brönsted acid sites. The number of the Brönsted acidic sites can be increased via a high-temperature hydrogenation process, which subsequently improves their catalytic performance in the Friedel–Crafts reaction of anisole and benzyl alcohol.
