ABSTRACT:
Porous microcomposites comprising a perfluorinated ion-exchange polymer (PFIEP) containing pendant metal cation exchanged sulfonate groups, metal cation exchanged carboxylate groups, or metal cation exchanged sulfonate and carboxylate groups, wherein the metal cation may be ligand coordinated, and optionally pendant sulfonic acid groups, carboxylic acid groups, or sulfonic acid and carboxylic acid groups, the PFIEP being entrapped within and highly dispersed throughout a network of metal oxide, a network of silica or a network of metal oxide and silica can be 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. Preferred metal cations are Cr, Sn, Al, Fe, Os, Co, Zn, Hg, Li, Na, Cu, Pd or Ru. 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.
