Silk fibroin supported Pd (Pd/SF) has been prepared and used as catalyst in Suzuki–Miyaura cross‐coupling reactions in water/ethanol (4:1 v/v) mixture. The reactions proceed rapidly with aryl iodides and boronic acids with different electronic properties using low metal loading (0.38 mol‐%). Pd/SF exhibits better recyclability compared to other biopolymer‐supported Pd catalysts, up to nineteen cycles without loss of activity.
