Herein, nitrogen-doped porous carbon materials were synthesized from dried ginkgo leaves through alkali activation and the subsequent heating treatment, during which ureophil with high nitrogen content was used
such as carbon nanotubes (625 mA h g−1) (ref.13), graphene (approximately 568 mA h g−1) (ref.14) and carbon nanotube and graphene composites15,16. In addition, partially graphitized porous carbon is a class of emerging materials...

Nitrogen-doped porous activated carbon monoliths (NDP-ACMs) have long been the most desirable materials for supercapacitors. Unique to the conventional template based Lewis acid/base activation methods, herein, we report on a simple yet practicable novel approach to production of the three-dimensional...

Nitrogen self-doped porous carbon materials with large surface area and excellent cycle stability are successfully synthesized from the waste of Pteroceltis tatarinowii Maxim (PTM) bark for the first time. During the synthesis procedure, ethanol is introduced to ensure a homogeneous mixture and good...
Moreover, the symmetric supercapacitor based on the porous carbon materials in neat DLC301 electrolyte delivers a high energy density of 58.75 Wh/kg and an excellent power density of 250 W/kg. Two assembled supercapacitors were connected and utilized for the driving recorder to work normally for ...
[155]. Nitrogen-dopedporous carbonmaterials can be derived by adopting two key strategies, (i) choosing the precursor materials with extensive nitrogen content and (ii) integrating the nitrogen-rich chemicals with biomasses. The biomasses such as natural silk[156], watermelon rind[157], pine ...
However, porous carbon materials possess large specific surface area, but the capacitance and rate performances are unsatisfactory due to large ion diffusion resistance and low available specific surface area. In addition, excessive activation of carbon materials will lead to a greatly decrease in ...
One approach to find a novel support is to dope porous carbon nanostructure materials with nitrogen. As is known, carbon nanostructure materials (e.g., CNT, CNF) have shown already promising potential applications in many fields [41], [42]: electronics, sensors, polymer composites, hydrogen sto...
