## Description

- description: 'Oxidative homocoupling of arenes is a challenging but attractive method
    converting non-activated aromatics into biaryl compounds. Applications and mechanistic
    understanding of bimetallic nanocatalysts for arene C–H bond activation are lim-ited
    at present. In this study, we found that Pd-Ru bimetallic catalyst supported on
    Al2O3 showed remarkably high catalytic activity for the oxidative homocoupling
    of arenes owing to the synergistic effect between Pd and Ru. Structural analyses
    by high-angle annular dark-field scanning transmission electron microscopy with
    energy dispersive X-ray spectroscopy and X-ray absorption spectroscopy revealed
    that Pd nanoparticles were decorated by partially oxidized Ru clusters. Mechanistic
    studies indicated that the arene C–H bond cleavage was the rate-determining step
    and proceeded by concerted metalation deprotonation mechanism. It was proposed
    that the role of Ru is promoting the C–H activation step by generating electron
    deficient Pd sites, which was supported by DFT calculations. The Ru-decorated
    Pd nanoparticles showed large turnover numbers for simple arenes. '
