High-efficiency PdNi single-atom alloy catalyst toward cross-coupling reaction

The preparation of Pd-based catalysts with rich electrons and a high atom dispersion rate is of great significance for improving the reactivity of cross-coupling reactions,which is a powerful tool for pharma-ceutical and fine chemical synthesis.Here,we report a PdNi single-atom alloy(SAA)catalyst in which iso-lated Pd single atoms are anchored onto the surface of Ni nanoparticles(NPs)applied for Suzuki coupling reactions and Heck coupling reactions.The 0.1% PdNi SAA exhibits extraordinary catalytic activity(reac-tion rate:17,032.25mmol h-1 gPd-1)toward the Suzuki cross-coupling reaction between 4-bromoanisole and phenylboronic acid at 80℃ for 1h.The excellent activity is supposed to attribute to the 100 percent utilization rate of Pd atoms and the highly stable surface zero-valance Pd atoms,which provides abun-dant sites and electrons for the adsorption and fracture of the C-X(X=Cl,Br,I)bond.Moreover,our work demonstrates the excellent application prospect of SAAs for cross-coupling reactions.
