Graphical Abstract

Benefits of instability: MOFs are used as metal ion precursors for the synthesis of nanocomposites by exploiting the instability of MOFs. The reaction occurs simply by mixing the MOFs, substrates, and other reactants (such as TAA and nickel nitrate). Through a heterogeneous growth process, nanomaterials with uniform structures can be formed on different substrates.

Abstract

Metal–organic frameworks (MOFs) are promising materials with fascinating properties. Their widespread applications are sometimes hindered by the intrinsic instability of frameworks. However, this instability of MOFs can also be exploited for useful purposes. Herein, we report the use of MOFs as metal ion precursors for constructing functional nanocomposites by utilizing the instability of MOFs. The heterogeneous growth process of nanostructures on substrates involves the release of metal ions, nucleation on substrates, and formation of a covering structure. Specifically, the synthesized CoS with carbon nanotubes as substrates display enhanced performance in a lithium-ion battery. Such strategy not only presents a new way for exploiting the instability of MOFs but also supplies a prospect for designing versatile functional nanocomposites.
