Periodic mesoporous organosilicas functionalized with sulfonic acid group. Synthesis and alkylation of phenol
Periodic mesoporous organosilicas have been successfully functionalized with sulfonic acid groups. The resulting materials exhibit much higher catalytic activity than ZSM-5 zeolite and higher catalytic stability than MCM-41 functionalized with the same group.
