文摘

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.
