Suzuki cross-coupling reactions activated by palladium (Pd) catalysts are efficient routes for the synthesis of useful organics. Traditional homogeneous ligand Pd catalysts face tedious separation process and are sensitive to the reaction environments. Here, we report an ultrasmall Pd cluster over the nitrogen-doped carbon materials. The strong electronic interaction between Pd and nitrogen not only suppresses the agglomeration of Pd metals during annealing process but also donates electrons to the Pd centers. The high atom utilization efficiency and electron-rich properties enable the Pd clusters display a high turnover frequency of 198 h(-1) for the Suzuki cross-coupling reactions under a mild condition, which is nearly 18-fold higher than the carbon black supported Pd nanocrystals (10.5 h(-1)). More important, no decay of the activity was observed after five recycle runs.
