Transforming waste biomass with an intrinsically porous network structure into porous nitrogen-doped graphene for highly efficient oxygen reduction
Abstract
Porous nitrogen-doped graphene with a very high surface area (1152 m 2 g −1 ) is synthesized by a novel strategy using intrinsically porous biomass (soybean shells) as a carbon and nitrogen source via calcination and KOH activation with outstanding oxygen reduction performance.

Significant weight loss of HC-KOH above 600 °C suggests carbon is severely etched by KOH to form a well-developed porous structure.
“there is a significant weight loss in the final stage above 600 ° C, suggesting that the carbon is severely etched by KOH to form the well-developed porous structure [46].”

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.
