Chem."],"abstract":"<jats:p>Contamination of phenolic compounds has devastating effects on the environment. Therefore, its harmless treatment and recycling have received extensive attention. Herein, a novel method for preparing N-S doped phenolic resin (NSPR) from phenols, N and S groups in semi-coking wastewater, and formaldehyde are developed. The KOH is consequently incorporated into the NSPR through simultaneous carbonization and activation in a single step to produce porous carbon material (NSPC). The as-obtained NSPC exhibits a high specific capacitance of 182\u00a0F\u00a0g<jats:sup>\u22121<\/jats:sup> at 0.5\u00a0A\u00a0g<jats:sup>\u22121<\/jats:sup>, a high energy density of 9.1\u00a0Wh kg<jats:sup>\u22121<\/jats:sup> at a power density of 0.15\u00a0kW\u00a0kg<jats:sup>\u22121<\/jats:sup>, and remarkable cycling stability in aqueous KOH electrolyte. This outstanding electrochemical performance is attributed to its ultrahigh specific surface area (SSA, 2,523\u00a0m<jats:sup>2<\/jats:sup>\u00a0g<jats:sup>\u22121<\/jats:sup>), enormous total pore volume (V<jats:sub>t<\/jats:sub>, 1.30\u00a0cm<jats:sup>3<\/jats:sup>\u00a0g<jats:sup>\u22121<\/jats:sup>), rational pore structure, and N-S heteroatom self-doping (0.76\u00a0at% N and 0.914 at% S), which ensures adequate charge storage, rapid electrolyte ion diffusion, and contributed pseudo-capacitance. This work not only provides a facile method for transforming phenolic wastewater into high-value products but also offers a cost-effective and high-performance porous carbon material for supercapacitors.<\/jats:p>","DOI":"10.3389\/fchem.2022.1021394","type":"journal-article","created":{"date-parts":[[2022,10,6]],"date-time":"2022-10-06T13:22:27Z","timestamp":1665062547000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Self-doped N, S porous carbon from semi-coking wastewater-based phenolic resin for supercapacitor electrodes"],"prefix":"10.3389","volume":"10","author":[{"given":"Long","family":"Yan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xianjie","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yufei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jian","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qianqian","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiang","family":"Zhong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuan","family":"Chang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qingchao","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Santosh Kumar","family":"Verma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2022,10,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1986","DOI":"10.3390\/ma12121986","article-title":"Novel synthesis of nitrogen-containing bio-phenol resin and its molten salt activation of porous carbon for supercapacitor electrode","volume":"12","author":"Ai","year":"2019","journal-title":"Mater.
