摘　　要：The synthesis of Pt-based nanoparticles(NPs)with ultrasmall feature and tailored structure is of great importance for catalysis yet challenging.In this work,we demonstrate a facile top–down strategy for the fabrication of small-sized Pt-based intermetallic compounds(IMCs)with L10 structure through the evaporation of Cd under high temperature.Impressively,such thermal treatment can be used as a versatile strategy for creating binary,ternary,quaternary,quinary,and senary L10-Pt-based IMCs.Moreover,the small-sized Pt-based IMCs display high stability against high temperature of 700℃,which can serve as active and selective catalyst for the selective hydrogenation of 4-nitrophenylacetylene.This work may not only provide a versatile top–down strategy for fabricating highly stable small-sized Pt-based NPs with L10 structure,but also promote their extensive applications in catalysis and beyond.
