Hydrogen peroxide-treated glycerol sourced porous carbon with elemental sulfur-based sulfur-phosphorus co-doping for CO capture.

In this work, glycerol and elemental sulfur-based porous carbon adsorbents with sulfur‑phosphorus co-doping and subsequent HO treatment were developed for CO capture. The best adsorbent for capturing CO among the developed adsorbents was P‑carbon-2000mgS-HO, which had surface area of 652 m/g, a total pore volume of 0.446 cm/g, an average pore size of 2.
