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.

Here, a high-performance HO electrochemical sensing platform is proposed based on an Au nanoparticles@UiO-66 film coated on a carbon cloth (CC) electrode (Au NPs@UiO-66/CC electrode). The Au NPs@UiO-66/CC electrode was prepared through solvothermal growth of a UiO-66 film on a functionalized three-dimensional CC electrode, followed by in situ deposition of Au NPs into the UiO-66 film under a periodic galvanostatic pulse current.

- A new method for creating hierarchical structures using metal-organic frameworks (MOFs) has been developed through programmed transformations.
- The method involves reacting a MOF precursor in different methanol solutions, leading to the creation of various morphologies, such as nanoneedles and nanosheets.
- The resulting hierarchical architecture showcases a quaternary structure—from the MOF unit cell to nanosheets, mesorods, and finally microcuboids—highlighting the potential for designing complex materials.
