A graphene-like N-doped hierarchical porous carbon array on a 3D metal substrate is obtained by a green and one-step vacuum de-metal assisted carbonization process for high performance potassium-ion batteries.
In the present work, a series of hierarchical porous carbon monoliths were prepared from fructoseviaa one-step ionothermal carbonization approach using an iron-based ionic liquid as solvent, and a porogenic agent.
A versatile strategy involving one-step desilication of coke-deposited spent zeolite catalyst was successfully developed to prepare hierarchical porous carbon monoliths (HPCMs).
The multi-hierarchical porous carbon was prepared using a general one-step method and assembled into symmetrical supercapacitors, exhibiting exceptional cyclic stability with 93.2% capacitance retention over 100 000 cycles.
A hierarchical porous carbon–carbon nanotube hybrid, which can be used as a high performance carbon host for sulfur, is formed in one step using a dual-functional hard template.
