Abstract：In this paper, taking advantages of the exchangeability of interlayer anions and the adjustability of metal cations in the lattices of layered double hydroxides (LDHs), ternary NiMgAl-LDHs with interlayer palladium-containing complex anions were synthesized. Highly dispersed carbon-supported bimetallic PdNi nanocatalysts were further fabricated through thermal hybridization of LDHs with glucose under hydrothermal conditions and following high-temperature self-reduction under inert atmosphere. A series of systematic characterizations reveal that uniform bimetallic PdNi nanoparticles in supported catalysts can be highly dispersed on the surface of supports, and the synergistic effect between Pd and Ni leads to the excellent catalytic performance of catalysts in the liquid-phase selective hydrogenation of citral.
