Gas-liquid interface-mediated room-temperature synthesis of 'clean' PdNiP alloy nanoparticle networks with high catalytic activity for ethanol oxidation

摘要

PdNiP alloy nanoparticle networks (PdNiP NN) were prepared by simultaneous reduction of PdCl_2, NiCl_2 and NaH_2PO_2 with NaBH_4 via a gas-liquid interface reaction at room temperature using N_2 bubbles. PdNiP NN had markedly higher activity and durability for ethanol oxidation than PdNi nanoparticle networks and PdNiP grain aggregates.
