摘要

Metal nanoparticles are extensively used as catalysts in heterogeneous catalysis.Microscopically,the surface of metal nanoparticles contains metal atoms located at the edges,comers and terraces of the lattice planes,presenting low-and high-coordinated metal atoms [1].These different locations lead to the different geometric and electronic structures of the sites,affecting the catalytic performances.These structure parameters (geometric and electronic struc-tures) change with particle size simultaneously,causing a remarkable particle size effect on catalytic reactions [2].Therefore,an activity-selectivity trade-off with particle size is often observed in a number of catalytic reactions,making the design of a highly selective and active metal catalyst challenging [3].
