Sulfonic Acid-Functionalized Inorganic Materials as Efficient Catalysts in Various Applications: A Minireview

Acid catalysis is widely used in the chemical industry, and nowadays many efforts are being focused on replacing more common homogeneous catalysts with heterogeneous ones order to make greener industrial processes. In this perspective, sulfonic solid acid materials represent a valid alternative homogenous mineral several catalyzed reactions. minireview, an overview of recent advances preparation, stability application these reported. Special attention addressed sustainability considered processes, starting from catalyst’s use green solvents reducing possible reaction steps. Ways tackle main drawback represented by easy leaching groups described. For catalyst recovery, magnetic core particle, related synthetic approaches, also illustrated. Finally, section dedicated principal characterization techniques identify structural properties catalysts.
