Peroxymonosulfate (PMS)-based advanced nonradical oxidation is a cutting-edge technology in environment remediation. However, the low graphitic N content greatly limits catalytic performance of N-doped graphene. Herein, almost theoretical upper-limited porous graphene (TUNPG) was obtained via pyrolysis melamine-cyanurate and 2-benzimidazolethiol at formation temperature 1000 °C. During pyrolysis, cyanuric acid decomposed into numerous N-containing gases, which exfoliated melamine-polymerized carbon nitride intermediates nanosheets. At °C, nanosheets were carbonized TUNPG with an 10.10 atom %, close to upper limit 12.5 %. The also possessed high proportion large Brunauer–Emmett–Teller surface area, enabling 6.6 times higher than that ultrahigh for degrading organics. Pathways PMS activation site theoretically explored. This work presents strategy fabrication carbonaceous materials offers insights 1O2 production atomic scale, providing new guidance developing various practical applications.

Nitrogen-doped graphene has been regarded as one of the most promising materials for nonradical peroxymonosulfate (PMS) activation. However, facile construction nitrogen-doped and systematic investigation its PMS activation in a practical environment still far lag behind. Herein, graphitic N-rich was prepared by one-step pyrolysis urea. The obtained urea-derived (UGNG) possessed high N content 12.12 at. % proportion 41.12%, giving 4.98 %. We confirmed that donated electrons to UGNG, resulting cleavage singlet oxygen oxidation. turnover frequency oxidation reached highest value 10.5 min–1. Also, reaction could be conducted wide temperature (5–45 °C) range, even with existence common matrix species different natural water matrixes. This work presented direct conversion organic urea UGNG systematically investigated activation, which is believed helpful further use.
