Nanosized ZnIn2S4 supported on facet-engineered CeO2 nanorods for efficient gaseous elemental mercury immobilization

Favorably adjusting the pore characteristics of copper sulfide by template regulation for vapor-phase elemental mercury immobilization

“…3,[8][9][10] Contrarily, elemental mercury (Hg 0 ), due to its high volatility and insolubility, persists in industrial ue gases and dominates the mercury species being emitted into the immediate environment. [11][12][13] Thus, to adequately fulll the obligations imposed by the Minamata Convention on Mercury and effectively mitigate anthropogenic Hg pollution, it is necessary to propose a pertinent solution to efficiently capture Hg 0 from industrial ue gases. 1,9 Metal suldes (MSs), with surfaces covered by abundant sulfur ligands, and an ability to convert Hg 0 into ultra-stable mercury sulde (HgS), were recently developed and are regarded as potential alternatives to traditional sorbents (e.g., activated carbons) for the Hg 0 removal from industrial ue gases.…”

A Molten-Salt Pyrolysis Synthesis Strategy toward Sulfur-Functionalized Carbon for Elemental Mercury Removal from Coal-Combustion Flue Gas

“…The Hg p can be captured by using particulate matter control devices, while the Hg 2+ can be removed by using wet flue-gas scrubbers due to Hg 2+ 's water solubility [9][10][11][12]. However, Hg 0 is difficult to remove owing to its water insolubility and high volatility [13][14][15]. As a consequence, Hg 0 is the primary species of mercury discharged into the atmosphere from coal-combustion flue gases.…”

Effects of Coal-Fired Flue Gas Components on Mercury Removal by the Mechanochemical S-Modified Petroleum Coke

“…Coal-fired power plants are considered one of the major anthropogenic emission sources of atmospheric mercury. 1 − 3 Mercury in coal-fired flue gas exists in three forms, including elemental mercury (Hg 0 ), oxidized mercury (Hg 2+, ) and particle mercury (Hg P ). 4 , 5 Hg P and Hg 2+ can be captured using the dust removal unit (an electrostatic precipitator or a bag filter) and wet flue gas desulfurization system, respectively.…”

“…Mercury emitted from coal combustion has attracted worldwide attention due to its high toxicity, volatility, environmental persistence, and biomass accumulation. Coal-fired power plants are considered one of the major anthropogenic emission sources of atmospheric mercury. − Mercury in coal-fired flue gas exists in three forms, including elemental mercury (Hg 0 ), oxidized mercury (Hg 2+, ) and particle mercury (Hg P ). , Hg P and Hg 2+ can be captured using the dust removal unit (an electrostatic precipitator or a bag filter) and wet flue gas desulfurization system, respectively. , However, Hg 0 is difficult to be removed and easily escapes into the atmosphere because of its volatility and insolubility. , The activated carbon injection (ACI) technology is considered to be a mature technology for mercury removal from coal-fired flue gas, while the high operation cost limits its wide application. − …”
