Exfoliation of layered double hydroxides (LDHs) into single layers provides a new
type of nanosheet with ultimate two-dimensional anisotropy and positive charge.
In this Highlight article, we briefly review the latest advances in this emerging
field. In comparison with the previous studies, we show that micrometer-sized and
well-defined LDH nanosheets can be readily attained by synthesizing large crystals
of LDH-carbonate via so-called homogeneous precipitation and subsequent
exfoliation of the nitrate form in formamide. Some general aspects including the
exfoliating process and characterization, a plausible delaminating mechanism,
and future challenges, are presented and discussed.
