Description of Publication:Highly efficient decontamination of elemental mercury (Hg0) remains an enormous challenge for ecosystem protection. The artificial conversion of Hg0 into mercury chalcogenides could achieve Hg0 detoxification and close the global mercury cycle. Herein, inspired by the detoxification of mercury in living organisms, in which selenium preferentially converts mercury from sulfoproteins to HgSe, a bionic approach is proposed to enhance the conversion of Hg0 into mercury chalcogenides. The relatively stable aromatic rings linked with sulfur provided weak adsorption of Hg0 on the PPS rather than the formation of metastable HgS, and the weakly adsorbed mercury subsequently migrated to adjacent selenium sites for permanent immobilization. The enrichment of biomimetic sulfur-selenium pairs afforded an unprecedented Hg0 adsorption capacity and uptake rate of 1621.9 mg g-1 and 1005.6 μg g-1 min-1, respectively, which are the highest recorded values among various benchmark materials.
