Mesoporous materials functionalized with sulfonic groups are interesting for use in biomass valorization reactions. These types of reactions generally involve bulky reagents and/or products and also require different levels of acidity to be catalyzed. The solids studied in this work can be modified according to the requirements of the reaction: they have the particularity of allowing the type of acid (Brønsted and/or Lewis) anchored to the surface and the density of the sites to be varied. This study presents the most important results of the synthesized mesoporous materials, which were characterized with various techniques with the aim of correlating the textural and structural properties, chemical composition and acidity of the catalysts.
