摘要: 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 synergistic effect core–shell NCs; their catalytic activities are much higher than those monometallic other NCs.
