carbon-bearing material
Carbon materials are very interesting precursors for the preparation of acid catalysts bearing sulfonic groups. The variability in surface composition, and hence in the hydrophobic/hydrophilic balance, textural properties (surface area and porosity), and morphology, confers to the carbon materials a versatility that allows the preparation of tailored acid catalysts. In this chapter, we will present a brief overview of the different carbon materials, with their properties and the methods for their modification, the procedures to introduce sulfonic groups and the available techniques for their characterization, as well as some examples of catalytic applications and the deactivation mechanisms detected for this kind of materials.
