A Versatile 2D Cellulose Platform Strategy from Natural Wood Scaffold

A woodcell wall with cellulose as the key scaffold isa naturalhierarchical lamellar structure. This wood-derived cellulose scaffoldhas recently attracted enormous attention and interest, but almostall efforts have been devoted to its whole tissue functionalization.Here, we report the short ultrasonic processing of a wood cellulosescaffold to directly generate 2D cellulose materials. The obtained2D cellulose nanosheets consist of many highly oriented fibrils denselyarranged and can be further converted to ultrathin 2D carbon nanosheets.The nanoparticles, nickel-iron layer double hydroxide nanoflowers,manganese dioxide nanorods, and zinc oxide nanostars, are successfullyloaded in the 2D nanosheet, providing a versatile 2D platform strategyfor excellent 2D hybrid nanomaterials.
