Abatement of mercury emission from coal-fired power plants remains a serious task for public health and environmental societies. Selenium functionalized metal-organic framework MIL-101 (Se/MIL-101) was prepared removal plants. The Se/MIL-101 exhibited remarkable adsorption capacity 148.19 mg·g-1, which about 154 to 705 times larger than that commercial activated carbons exclusively applied initial rate reached up 44.8 μg·g-1·min-1, 89- 1659-fold higher those sorbents reported in the...
Abstract Biochar produced from pyrolysis of biomass has been developed as a platform carbonaceous material that can be used in various applications. The specific surface area (SSA) and functionalities such N-containing functional groups biochar are the most significant properties determining application performance carbon areas, removal pollutants, adsorption CO 2 H , catalysis, energy storage. Producing with preferable SSA N is among frontiers to engineer materials. This study attempted...
Transition Metal sulfides (TMSs) are effective sorbents for entrapment of highly polluting thiophiles such as elemental mercury (Hg0). However, the application these removal is stymied by their low accommodation capacities. Among transition metal sulfides, only CuS has demonstrated industrially relevant capacity. The rest have 100-fold lower capacities than CuS. In this work, we overcome limitations and develop a simple scalable process to enhance Hg0 TMSs. We achieve introducing structural...
Highly efficient decontamination of elemental mercury (Hg
Nanostructured copper sulfide synthesized with the assistance of surfactant nanoscale particle size and high Brunauer–Emmett–Teller surface area was for first time applied capture elemental mercury (Hg0) from coal combustion flue gas. The optimal operation temperature nano-CuS Hg0 adsorption is 75 °C, which indicates that injection sorbent between wet gas desulfurization electrostatic precipitator systems feasible. This assures free adverse influence nitrogen oxides. Oxygen (O2) sulfur...
Mercury emission from industrial activities is a great threat to public health and ecosystems. Developing new strategies materials remove mercury still remains serious task. Herein, selenide-decorated copper foam prepared by heating-stirring method (Cu-hs) was used as monolithic adsorption material. The Cu-hs exhibited much better of elemental (Hg0) compared with the cordierite honeycomb same (Cordierite-hs). Nearly 100% Hg0 efficiency obtained under high gaseous hourly space velocity 6.0 ×...
Rattle-type Fe3O4@CuS synthesized using a two-step method was applied for elemental mercury (Hg0) adsorption in coal combustion flue gas the first time. The Fe3O4 with strong magnetization an ideal candidate as core to make sorbent recyclable, while stabilized ultrathin CuS shell assured that had higher Brunauer–Emmett–Teller (BET) surface area more exposed active sites and stronger magnetization. optimal operating temperature of 75 °C allowed injection between wet desulfurization (WFGD)...
Abstract A key challenge in elemental mercury (Hg 0 ) decontamination from flue gas lies the design of a sorbent with abundant reactive adsorption sites that exhibit high affinity toward Hg to simultaneously achieve rapid capture and large capacity. Herein, zeolitic imidazolate framework‐8 (ZIF‐8) supported copper selenide (CuSe) nanocomposites are synthesized by newly designed two‐step surfactant‐assisted method. The as‐prepared CuSe/ZIF‐8 CuSe ZIF‐8 mass ratio 80% (0.8NC‐ZIF) exhibits...
The paramount challenge in design and synthesis of materials for vapor-phase elemental mercury (Hg0) immobilization is to achieve a balance between performance economy practical applications. Herein, newly designed electroless plating coupled with an situ selenization method was developed construct copper selenide (Cu2Se)-functionalized commercial polyurethane sponge (PUS) as efficient Hg0 trap. Intrinsic features such easy availability the raw material, facile preparation, excellent...
Metal selenides have been demonstrated as promising Hg0 remediators, while their inadequate adsorption rate primarily impedes application feasibility. Based on the critical role of coordinatively unsaturated selenide ligands in immobilizing Hg0, this work proposed a novel strategy to enhance metal by magnitudes purposefully adjusting saturation. Copper iron diselenide (CuFeSe2), which surface reconstruction tended occur at ambient temperature, was adopted concentrator selenides. The CuFeSe2...
Abstract The key challenge of vapor‐phase elemental mercury (Hg 0 ) sequestration is the rational design a sorbent with abundantly available ligands that exhibit excellent affinity toward Hg to simultaneously achieve high uptake capacity and rapid capture rate. In this work, it demonstrated how correct combination functional structural properties can form an ideal remediator for permanent immobilization. adsorption amorphous molybdenum triselenide (MoSe 3 nanosheet greater than 1000 mg g −1...
