Abstract
Heteroatoms doped porous carbon materials exhibit enormous potentiality in the field of energy storage field. Herein, we developed a facile strategy for preparing oxygen/nitrogen/sulfur co-doped porous carbon using acesulfame potassium as sulfur, nitrogen source and activator, polyacrylamide as carbon and nitrogen source. Benefiting from the suitable specific surface area and a certain amount of nitrogen (4.52 at%), oxygen (5.49 at%) and sulfur (0.28 at%) functional groups, the obtained ONSPC-700 samples exhibit a specific capacitance of 282.0 F g−1 and superior electrochemical stability with a high capacitance retention of 97.3% after 10,000 cyclic testing. Furthermore, the constructed ONSPC-700//ONSPC-700 symmetrical supercapacitor displays an energy density of 14.5 Wh kg−1 and superior electrochemical stability with a high capacitance retention of 95.8% after 10,000 cyclic testing. More importantly, the assembled Zn//ZnSO4//ONSPC-700 hybrid capacitor achieves an energy density of 86.2 Wh kg−1 and a high capacitance retention of 95.1% after 6000 cyclic testing. The research provides a novel and facile way for preparing heteroatoms doped porous carbon for energy storage device.
期刊介绍:
The Journal of Porous Materials is an interdisciplinary and international periodical devoted to all types of porous materials. Its aim is the rapid publication
of high quality, peer-reviewed papers focused on the synthesis, processing, characterization and property evaluation of all porous materials. The objective is to
establish a unique journal that will serve as a principal means of communication for the growing interdisciplinary field of porous materials.
Porous materials include microporous materials with 50 nm pores.
Examples of microporous materials are natural and synthetic molecular sieves, cationic and anionic clays, pillared clays, tobermorites, pillared Zr and Ti
phosphates, spherosilicates, carbons, porous polymers, xerogels, etc. Mesoporous materials include synthetic molecular sieves, xerogels, aerogels, glasses, glass
ceramics, porous polymers, etc.; while macroporous materials include ceramics, glass ceramics, porous polymers, aerogels, cement, etc. The porous materials
can be crystalline, semicrystalline or noncrystalline, or combinations thereof. They can also be either organic, inorganic, or their composites. The overall
objective of the journal is the establishment of one main forum covering the basic and applied aspects of all porous materials.
