BackgroundrnMetal nanoparticles (M-NPs) have attracted tremendous interest in recent years due to their unique physical and chemical properties resulting from their size reduction and shape variation.[1] In particular,the use of ultra-small M-NPs as efficient catalysts in various reactions is a rapidly growing area of research as a consequence of their synthetic accessibility and superior catalytic efficiency.[2] However,due to their high surface energy,small M-NPs are prone to aggregation during reactions and associated loss of their catalytic activities.To deal with this difficulty,various stabilizers and/or supports have been developed,for instance,small organic ligands,dendritic architectures,and polymers.Unfortunately,these materials all have limitations,such as low stability,constant leaching,irregular distribution or regrowth and combinations of these.Therefore,it is highly desirable to develop superior support materials that can overcome these issues.
