Sub-5 nm Porous Nanocrystals:Interfacial Site-Directed Growth on Graphene for Efficient Biocatalysis

摘要：

　　An interfacial site-directed,capping-agent-free growth method to directly produce ultrasmall porous(sub-5 nm),fully crystalline,marcomolecular scale nanocrystals is reported.The porous,sub-5 nmPrussian blue nanocrystals exhibit uniform sizes(~4 ± 1 nm),high surface area(~855 m2/g),fast electron transfer(rate constant of~9.73 s-1),and outstanding sustained catalytic activity(more than 450 days).The nanocrystal-based biointerfaces enable unprecedented sub-nanomolar level recognition for hydrogen peroxide(~0.5 nM limit of detection).This method also paves the way towards creating ultrasmall porous nanocrystals for efficient biocatalysis.
