Co9S8 nanoparticles-embedded porous carbon: A highly efficient sorbent for mercury capture from nonferrous smelting flue gas
In this study, a novel Co9S8 nanoparticles-embedded porous carbon (Co9S8-PC) was designed as an effective reusable sorbent for Hg0 capture from smelting flue gas. Some flue gas components can create more active sites on Co9S8-PC for Hg0 adsorption, but compete with Hg0 for the same sulfur sites over...

| 520 | |a In this study, a novel Co9S8 nanoparticles-embedded porous carbon (Co9S8-PC) was designed as an effective reusable sorbent for Hg0 capture from smelting flue gas. Some flue gas components can create more active sites on Co9S8-PC for Hg0 adsorption, but compete with Hg0 for the same sulfur sites over nano Co1−xS/Co3S4 (CoS) and Co1−xS/Co3S4 embedded porous carbon (CoS-PC), which can be ascribed to the difference in crystal structure between Co9S8 and Co1−xS/Co3S4. Therefore, Co9S8-PC shows much better Hg0 capture ability than CoS and CoS-PC under smelting flue gas. O2, SO2 and HCl improve Hg0 adsorption on Co9S8-PC mainly through creating Co3+ site, but H2O has neglectable effect on Hg0 capture. Co9S8-PC shows a remarkably large Hg0 adsorption capacity of 43.18 mg/g, which is greatly higher than the representative metal sulfides for Hg0 removal from smelting flue gas. During Hg0 adsorption, Co3+ is the primary site to directly interact with Hg0, and the adsorbed mercury exists as HgS. Co9S8-PC exhibits an excellent recyclability for capturing Hg0, which is mainly assigned to the replenishment of consumed Co3+ site by O2, SO2 and HCl. Therefore, Co9S8 nanoparticles-embedded porous carbon is an efficient, sustainable and highly recyclable sorbent for Hg0 recovery from smelting flue gas. | ||

During Hg0 adsorption, Co3+ is the primary site to directly interact with Hg0, and the adsorbed mercury exists as HgS. Co9S8-PC exhibits an excellent recyclability for capturing Hg0, which is mainly assigned to the replenishment of consumed Co3+ site by O2, SO2 and HCl. Therefore, Co9S8 nanoparticles-embedded porous carbon is an efficient, sustainable and highly recyclable sorbent for Hg0 recovery from smelting flue gas.

Co9S8 nanoparticles-embedded porous carbon: A highly efficient sorbent for mercury capture from nonferrous smelting flue gas |
| abstract |
In this study, a novel Co9S8 nanoparticles-embedded porous carbon (Co9S8-PC) was designed as an effective reusable sorbent for Hg0 capture from smelting flue gas. Some flue gas components can create more active sites on Co9S8-PC for Hg0 adsorption, but compete with Hg0 for the same sulfur sites over nano Co1−xS/Co3S4 (CoS) and Co1−xS/Co3S4 embedded porous carbon (CoS-PC), which can be ascribed to the difference in crystal structure between Co9S8 and Co1−xS/Co3S4. Therefore, Co9S8-PC shows much better Hg0 capture ability than CoS and CoS-PC under smelting flue gas. O2, SO2 and HCl improve Hg0 adsorption on Co9S8-PC mainly through creating Co3+ site, but H2O has neglectable effect on Hg0 capture. Co9S8-PC shows a remarkably large Hg0 adsorption capacity of 43.18 mg/g, which is greatly higher than the representative metal sulfides for Hg0 removal from smelting flue gas. During Hg0 adsorption, Co3+ is the primary site to directly interact with Hg0, and the adsorbed mercury exists as HgS. Co9S8-PC exhibits an excellent recyclability for capturing Hg0, which is mainly assigned to the replenishment of consumed Co3+ site by O2, SO2 and HCl. Therefore, Co9S8 nanoparticles-embedded porous carbon is an efficient, sustainable and highly recyclable sorbent for Hg0 recovery from smelting flue gas. |

Therefore, Co9S8-PC shows much better Hg0 capture ability than CoS and CoS-PC under smelting flue gas. O2, SO2 and HCl improve Hg0 adsorption on Co9S8-PC mainly through creating Co3+ site, but H2O has neglectable effect on Hg0 capture. Co9S8-PC shows a remarkably large Hg0 adsorption capacity of 43.18 mg/g, which is greatly higher than the representative metal sulfides for Hg0 removal from smelting flue gas. During Hg0 adsorption, Co3+ is the primary site to directly interact with Hg0, and the adsorbed mercury exists as HgS. Co9S8-PC exhibits an excellent recyclability for capturing Hg0, which is mainly assigned to the replenishment of consumed Co3+ site by O2, SO2 and HCl. Therefore, Co9S8 nanoparticles-embedded porous carbon is an efficient, sustainable and highly recyclable sorbent for Hg0 recovery from smelting flue gas.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Flue gas</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Porous carbon</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Mercury capture</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Nonferrous metallurgy</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Co9S8</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Cao</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Pingshan</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yi, Huimin</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shen, Fenghua</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Hui</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="n">Science Direct</subfield><subfield code="a">Moreira-González, Angel R.
