Description of Publication:The key challenge to abate the mercury emission is to explore high efficient adsorbent. Herein, sulfur-functionalized carbon (S-C) was synthesized by a molten salt pyrolysis strategy and employed for the removal of elemental mercury from coal combustion flue gas. An ideal pore structure, which was favorable for internal diffusion of Hg0 molecule in carbon, was obtained by using SiO2 hard template and adjusting the HF etching time. The mechanism of the Hg0 removal by S-C was proposed, i.e., the reduced including sulfur thiophene, sulfoxide and C-S displayed high affinity toward Hg0, which could guarantee the stable immobilization of Hg0 as HgS in the adsorbent. Thus, the molten salt pyrolysis strategy has a broad prospect in the application of one-pot carbonization and functionalization sulfur-containing organic precursor as efficient adsorbents for Hg0.
