Clay-supported novel bimetallic core–shell Co–Pt and Ni–Pt nanocrystals with high catalytic activities†
Abstract
We demonstrate the striking potential of exfoliated clay (synthetic hectorite; Laponite XLG) platelets to prepare bimetallic (Co–Pt and Ni–Pt) NCs with well-defined structures. Catalytic studies show a strong bimetallic synergistic effect of the core–shell NCs; their catalytic activities are much higher than those of monometallic NCs and other bimetallic core–shell NCs.
