Pd-Ni bimetallic nanoparticles supported on ZrO2 as an efficient catalyst for Suzuki-Miyaura reactions

Pd-Ni bimetallic nanoparticles (BMNPs) supported on ZrO2 were prepared by an impregnation-reduction method. The BMNPs showed excellent catalytic performance in Suzuki carbon-carbon cross-coupling reactions and almost quantitative conversion of the substrates was obtained under mild conditions in the absence of ligand. The excellent catalytic performance of the bimetallic catalyst could be a result of the synergistic effect between the two metal components. The catalyst showed outstanding recyclability during the reaction process; no obvious decrease in catalytic performance was observed after five cycles.
