Superlong Metal-Organic Framework Nanowire Fabricated via Steam-Assisted Conversion

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. A facile steam-assisted conversion is developed to fabricate superlong 1D Cu metal-organic framework (MOF) nanowire through recrystallization mechanism. As-prepared 1D Cu MOF nanowire possesses identical crystal structure of MOF-74 and multiscale porous structure, which can effectively remove cationic dyes and is an ideal template to form Cu nanoparticle-doped carbon nanofiber with excellent electrocatalytic activity for glucose detection. image
