简介：Among various metal sulfides, copper sulfide (CuS) was found to be the most efficient one for the abatement of elemental mercury (Hg0) pollution in coal combustion flue gas because of the enrichment of under-coordinated sulfur along the <001> direction. But how to effectively synthesize (001) surface exposed CuS through a facile method has long been challenging in the Hg0 controlling community. In this work, a feasible synthesis strategy based on mechanical ball-milling procedure was proposed to synthesize (001) surface exposed CuS under mild conditions. Consequently, the CuS as obtained exhibited the Hg0 adsorption capacity and uptake rate as high as 86.22 mg g-1 and 112.04 μg g-1 min-1. This facile synthesis logic with scale-up potential may also be applicable in the preparation of other metal sulfides in addition to CuS, marking an effective attempt stepping towards the industrial application of metal sulfides for Hg0 immobilization from coal combustion flue gas.
