Ultrahigh surface area carbon nanosheets derived from lotus leaf with super capacities for capacitive deionization and dye adsorption

High surface area, suitable pore size distribution and good wettability of carbonaceous materials are crucial for a variety of surface and interfacial interaction-related applications. Herein, hydrophilic porous carbon nanosheet with an ultrahigh surface area (4482 m2 g−1) was prepared using lotus leaf (LL) as the carbon source. It was revealed that the surface area and microporosity are dependent on the reactivity of the precursor, which can be...
