Superlong Metal‐organic Framework Nanowire Fabricated via Steam‐assisted Conversion

Abstract

1D nanomaterials have attracted great attention due to their outstanding anisotropic and linear structures. A facile method is developed to fabricate 1D copper metal‐organic framework nanowires (Cu‐MOF‐NW) through steam‐assisted conversion from Cu‐MOF precursors. During the steam‐assisted conversion, Cu‐MOF precursor gradually dissolves in methanol steam, and then recrystallized into Cu‐MOF‐NW, which shows high aspect ratio of about 600 and identical crystal structure of MOF‐74. As‐prepared Cu‐MOF‐NW with multiscale porous structure can effectively remove cationic dyes even in dye mixture. Moreover, Cu‐MOF‐NW, as an ideal template, is calcined to form Cu nanoparticle‐doped carbon nanofiber with maintaining its 1D morphology, which shows excellent electrocatalytic activity for the non‐enzymatic sensing of glucose.
