英文摘要A rational design of the intrinsic lattice structure of catalysts is vitally important to address catalytic perfor-mance. Herein is reported a top-down synthesis for the fabrication of a bifunctional metallic catalyst. First, palladium nanocubes with (100) lattices planes were synthesized through a shape-control strategy; next, the as -synthesized Pd/Co-ZIF was used as a template for in -situ phase reconstruction by a spontaneous phase trans-formation process in the presence of H4SiW under solvothermal conditions. Ultimately, formation of 3D hier-archical flower-like bimetallic nitride nanosheets (SiW12 @Pd/Co-ZIF-NS) were generated because of this process. The SiW12 @Pd/Co-ZIF-NS catalyst not only displays excellent catalytic transfer hydrogenolysis for C-O bond cleavage of lignin dimeric substrates, but also maintains superior recycling durability due to an encapsu-lation phenomenon preventing aggregation. Finally, the resulting nanocomposites exhibit superior activity and good size selectivity toward catalytic transfer hydrogenolysis of the actual lignin substrates to produce a sig-nificant amount of low-molecular-weight aromatic compounds.
