Amino-functionalized SiO2-PSSA nanocomposites were prepared by sol-gel routes.
Amino-functionalization aimed at minimizing the polymer leaching.
These inorganic-organic nanohybrids were tested as acid catalysts in two reactions.
Extensive polymer leaching was observed when used in xylose to furfural reaction.
Leaching of polymer was much less intense in the biodiesel synthesis reaction.
