Grafting nanometer metal/oxide interface towards enhanced low-temperature acetylene semi-hydrogenation.

ABSTRACT: Metal/oxide interface is of fundamental significance to heterogeneous catalysis because the seemingly "inert" oxide support can modulate the morphology, atomic and electronic structures of the metal catalyst through the interface. The interfacial effects are well studied over a bulk oxide support but remain elusive for nanometer-sized systems like clusters, arising from the challenges associated with chemical synthesis and structural elucidation of such hybrid clusters. We hereby demonstrate the essential catalytic roles of a nanometer metal/oxide interface constructed by a hybrid Pd/Bi₂O₃ cluster ensemble, which is fabricated by a facile stepwise photochemical method. The Pd/Bi₂O₃ cluster, of which the hybrid structure is elucidated by combined
