Abstract
We report a general and efficient
strategy to produce monodisperse
transition-metal (Mn, Co, and Ni) hydroxide nanoplates with tunable
composition through the interface-mediated growth process. It is worth
noting that, using common nitrates as the precursors, the as-obtained
nanoplates were prepared under hydrothermal conditions. Moreover,
the possible formation mechanism of the transition-metal hydroxide
nanoplates has also been investigated. Subsequently, the resulting
transition-metal hydroxides can be eventually transformed into transition-metal
oxide nanoplates and lithium-ion intercalation materials through solid-state
reactions, respectively. Furthermore, the electrochemical properties
of the resulting nanomaterials have also been discussed in detail.
This protocol may be easily extended to fabricate many other metal
hydroxide and oxide nanomaterials
