doped silica (Pd/SiO2) mesoporous material was synthesized via the sol–gel route using the P123 triblock copolymer as a structure directing agent. Pd/SiO2 was efficiently used as a catalyst for Suzuki, Heck and Sonogashira reactions under microwave irradiation. The catalyst exhibited high activity for all the coupling reactions and can be recycled nine times without a significant loss in its catalytic activity
