简介：A key challenge in elemental mercury (Hg0) decontamination from flue gas lies in the design of a sorbent with abundant reactive adsorption site that exhibits high affinity towards Hg0 to achieve rapid capture and large capacity simultaneously. Herein, the zeolitic imidazolate framework-8 (ZIF-8) supported copper selenide (CuSe) nanocomposites were synthesized by a newly designed two-step surfactant-assisted method. The as-prepared CuSe/ZIF-8 with CuSe to ZIF-8 mass ratio of 80% (0.8NC-ZIF) established unparalleled performance towards Hg0 adsorption with equilibrium capacity and average rate reaching 309.8 mg g-1 and 105.3 μg g-1 min-1, respectively, surpassing all reported metal sulfides and traditional activated carbon based sorbents.This work provides a new mindset for future design of sorbents for efficient Hg0 capture from industrial flue gas. The results also justify the candidature of CuSe/ZIF to be applicable for mercury pollution remediation in a real-world condition.
