Potassium compound-assistant synthesis of multi-heteroatom doped ultrathin porous carbon nanosheets for high performance supercapacitors
Open accessAbstract
Two-dimensional (2D) porous carbon materials have attracted great attentions as high-performance electrodes for supercapacitors due to their large aspect ratio and high surface area. Generally, micropore-dominant 2D carbon materials have higher densities than hierarchically porous 3D carbon materials, which can provide a new possibility of greatly enhancing the volumetric capacitance. Herein, we propose a facile and low-cost synthesis method of biomass-derived porous carbon nanosheets (PCNSs) with the assistance of the KOH derived potassium compounds using fish scale as precursor. The PCNS obtained at 600 °C possesses ultrathin nanosheet structure (with thickness of 3–5 nm), micropore-dominate porosity (with specific surface area of 962 m2 g−1), rich surface heteroatoms (14.64 at% for O, 5.05 at% for N and 0.92 at% for S) and high compacting density (1.06 g cm−3), which endow the electrodes with high gravimetric/volumetric capacitance performance in three-electrode and two-electrode systems.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
