The exfoliated 2D nanosheets of layered metal compounds (layered metal oxides, layered double hydroxides, transition metal dichalcogenides, and layered metal carbides) attract intense research interest because of their unique physicochemical properties and useful functionalities.  The 2D inorganic nanosheets can be synthesized by soft-chemical exfoliation reaction and used as efficient 2D lego blocks for superlattice nanohybrids, porous nanocomposites, multilayered films, freestanding hybrid films, etc.  The resulting 3D hybrid materials possess diverse promising applicabilities for energy and environmental technologies.  In this talk, versatile use of exfoliated inorganic nanosheets as 2D lego blocks will be presented together with the application of inorganic nanosheet-based nanohybrids with tailorable physicochemical properties and functionalities such as electrode activity, photocatalytic activity, redox catalytic activity, electrocatalytic activity, gas adsorption capability, and nanobio application.
