Tailoring Metal-Oxide Interfaces via Selectively CeO₂-Decorated Pd Nanocatalysts with Enhanced Catalytic Performance.

ABSTRACT: Metal-oxide interfaces play a prominent role in heterogeneous catalysis. Tailoring the metal-oxide interfaces effectively enhance the catalytic activities and thermal stability of noble metal catalysts. In this work, polyvinyl alcohol-protected reduction and L-arginine induction methods are adopted to prepare Pd catalysts (Pd/Al₂O₃-xCeO₂) that are selectively decorated by CeO₂, which form core-shell-like structures and generate more Pd-CeO₂ interfacial sites, so that the three-way catalytic activity of Pd/Al₂O₃-xCeO₂ catalysts is obviously significantly enhanced due to more adsorption oxygen at the interface of Pd-CeO₂ and good low-temperature reducibility. At the moment, the Pd/Al₂
