nanosheets [Figure 8]. Two-dimensional cobaltate nanosheets obtained by this “self-deconstruction/
reconstruction” strategy exhibit high surface areas and narrow pore size distributions.
Nevertheless, due to the mesopores originating from the pores between or within particles of the material, a
template-free method generally lacks the ability to control the size and structure of pores and often can only
obtain disordered mesopores.
CONCLUSION AND OUTLOOK
In this paper, the progress and achievements in the preparation of 2DMMs from self-assembly methods in
the past ten years are reviewed. A self-assembled synthetic strategy provides flexible control over the
morphology and pore size/shape of 2DMMs. The current popular synthesis methods are discussed,
