Cover Story: Selective aerobic oxidation of benzylic compounds to construct carbonyl compounds is a challenge in both academia and industry. In this work, Au-Pd nanoparticles supported on porous carbon were fabricated by the borax-mediated hydrothermal carbonization and chemical reduction process. The bimetallic Au-Pd nanocatalysts displayed an outstanding catalytic activity (76% conversion, >99% selectivity toward indanone) in the solvent-free oxidation of indane into indanone under 1 bar O2. The synergistic effect of Au and Pd and porous carbon support contributed to the high catalytic activity for aerobic benzylic compound oxidation. A possible reaction pathway was proposed. This work provided a useful strategy to design efficient and recyclable noble metal-based nanocatalysts in functional benzylic ketone production. View this paper
