简介：The major challenge to use metal sulfide for elemental mercury (Hg0) immobilization from coal-fired flue gas is exploiting a facile and feasible pathway to achieve its fixed-bed application. In this work, copper sulfide (Cu7S4) nanosheet arrays anchored on copper skeleton as an efficient Hg0 trap with outstanding Hg0 sequestration performance was rapidly fabricated via a facile room-temperature chemical bath deposition method. Benefitted from well arrayed Cu7S4 nanosheet, high-permeability structure, and uniform dispersion of active sites, the as-obtained Cu7S4/Copper foam favors for its application in Hg0 immobilization under a fixed-bed circumstance. These superiorities contribute to its outstanding Hg0 removal capacity of 38.32 mg g-1and adsorption rate of 6.06 μg g-1 min-1, far transcending that of commercial granular S impregnated activated carbon by magnitudes.
