Description of Publication:Nanostructured copper sulfide synthesized with the assistance of surfactant with nano-scale particle size and high Brunauer-Emmett-Teller surface area was for the first time applied for the capture of elemental mercury (Hg0) from coal combustion flue gas. The optimal operation temperature of Nano-CuS for Hg0 adsorption is 75 °C, which indicates that injection of the sorbent between the wet flue gas desulfurization and the wet electrostatic precipitator systems is feasible.The adsorption capacities of Nano-CuS for Hg0 under pure nitrogen (N2), N2 plus 4% O2, and simulated flue gas reached 122.40, 112.06, and 89.43 mg Hg0/g Nano-CuS, respectively.The anisotropic growth of Nano-CuS was confirmed by X-ray diffraction analysis and provided a fundamental aspect for Nano-CuS surface reconstruction and polysulfide formation.With these advantages, Nano-CuS appears to be a highly promising alternative to traditional sorbents for Hg0 capture from coal combustion flue gas.
