Preparation of high-performance carbon materials with an abundance of heteroatoms, edges, and defects for sustainable energy-conversion technologies, such as supercapacitors and oxygen reaction reduction (ORR), are still a challenge. Herein, we reported a facile strategy for the large-scale synthesis of nitrogen-doped porous carbon via carbonization of core-shell structured protonated g-C3N4@polypyrrole...
This work reports a facile strategy for the preparation of Nitrogen-doped porous carbons via carbonization of a mixture containing ferric citrate (FC) and ammonium chloride (NH4Cl). FC provides carbon and iron element sources, while ammonium chloride acts as both the porogen and nitrogen dopant during the carbonization process. The formed hierarchical porous structures facilitate the ion diffusion/transport,...
Graphene oxide (GO) has recently been identified as an excellent candidate for membrane science, but the relatively small number of channels for species to transport across the laminated GO membranes is one of the major limitations for the membrane permeability. Thus, engineering porous structures on GO sheets, such as pores and notched edges, is a promising solution to increase channels across the...
A facile and efficient strategy for the synthesis of heteroatom-doped carbon materials was developed, in which host–guest inclusion complexes were employed as versatile precursors. Inclusion of heteroatom containing guest molecules in the cavity of host molecules (such as cyclodextrins and cucurbit[n]urils) not only doped the carbon frameworks with heteroatoms (for instance, nitrogen, sulfur, boron,...
In situ boron or nitrogen doping in chemical vapor deposition growth of graphene on Cu (111) surface was extensively investigated by first-principles calculations. It was found that, during graphene growth, both boron and nitrogen atoms can be incorporated onto the graphene edge by overcoming the medium barriers of 1.50 and 1.95 eV, respectively. And, once a boron or nitrogen atom has been embedded...
