Abstract：

Monolayered 2D nanosheets of layered metal compounds (layered metal oxides, layered double hydroxides, transition metal dichalcogenides, and layered metal carbides) have attracted intense research interest because of their unique physicochemical properties and useful functionalities.  These monolayered inorganic nanosheets can be synthesized by soft-chemical exfoliation reaction and used as efficient 2D building blocks for superlattice nanohybrids, porous nanocomposites, freestanding hybrid films, etc.  The wide 2D surface area, very thin thickness, and high electrochemical and catalytic activities render these inorganic nanosheets promising materials for energy production and storage.  In this talk, versatile roles of 2D inorganic nanosheets in multifunctional nanohybrids will be presented together with in-depth analysis for the relationship between chemical bonding nature and energy functionality.
