ABSTRACT:
Porous microcomposites comprising a perfluorinated ion-exchange polymer (PFIEP) containing pendant sulfonic acid and/or carboxylic acid groups entrapped within and highly dispersed throughout a network of metal oxide, a network of silica, or a network of metal oxide and silica are prepared from PFIEP and one or more precursors selected from the group consisting of a metal oxide precursor, a silica precursor, and a metal oxide and silica precursor using an in situ process. Such microcomposites have a first set of pores having a pore size diameter ranging from about 0.5 nm to about 75 nm and may further comprise a second set of pores having a diameter ranging from about 75 nm to about 1000 nm. These microcomposites possess high surface area and exhibit high catalytic activity for a variety of reactions including, but not limited to, nitrations, esterifications, dimerizations, alkylations, polymerizations, acylations, and isomerizations.
