Abstract

Abstract : By calcining melamine at 500 °C with selenium powder as the structure director, polymeric carbon nitride could be prepared with enhanced specific surface area and mesoporous volume. Compared with the material fabricated without Se, this cost‐effective Se‐incorporated PCN (PCN‐Se) could adsorb heavy metals (such as Ni, Cu and Pb) much more efficiently. Materials characterizations such as SEM, TEM and XPS demonstrated that the enlarged specific surface area and total mesoporous volume as well as the interaction of the incorporated Se with the metals via coordination should be the promoting factors for the advanced performances of the novel materials. Abstract : A novel method for enhancing the specific area of PCN by doping Se was developed. In comparison with simple PCN, the PCN‐Se with enhanced specific area could adsorb even more metal, affording an advanced material for wastewater treatment.
