Porous Fe, N co-doped carbon with high electrocatalytic oxygen reduction reaction performance in Zn-air battery
Non-Pt electrocatalysts for oxygen reduction reactions (ORR) have been developed using metal and nitrogen co-doped carbon electrocatalysts. However, challenges remain regarding the porosity of the catalyst, distribution of active sites, and the easy aggregation of the metal components. Herein, we re...

| 520 | |a Non-Pt electrocatalysts for oxygen reduction reactions (ORR) have been developed using metal and nitrogen co-doped carbon electrocatalysts. However, challenges remain regarding the porosity of the catalyst, distribution of active sites, and the easy aggregation of the metal components. Herein, we report a bottom-up preparation strategy to obtain a porous ethynyl-linked conjugated microporous polymer (CMP) precursor containing triazine units and bipyridine, ensuring high N content and coordination with Fe3+. The Fe doped CMP is then carbonization into a Fe, N co-doped nanoporous carbon material (BPCMP-Fe-800), which can be taken as the electrocatalyst in ORR. BPCMP-Fe-800 catalyst exhibits electrocatalytic performance dominated by 4e− transfer mechanism with the onset potential of 0.97 V, half-wave potential of 0.85 V, and higher kinetic current density of 11.3 mA cm−2 (0.8 V). In addition, when applied as cathode electrocatalyst in zinc-air batteries, BPCMP-Fe-800 displays more competitive power density (179.5 mW cm−2) and specific capacity (790.5 mAh g−1) compared with Pt/C. Our study demonstrates a general and facile approach for porous Fe, N co-doped carbon with the potential as alternatives to Pt catalysts for efficient ORR catalytic performances and provides new insights of multi-atom catalysts for other energy conversion related catalytic reactions. | ||

Porous Fe, N co-doped carbon with high electrocatalytic oxygen reduction reaction performance in Zn-air battery |
| abstract |
Non-Pt electrocatalysts for oxygen reduction reactions (ORR) have been developed using metal and nitrogen co-doped carbon electrocatalysts. However, challenges remain regarding the porosity of the catalyst, distribution of active sites, and the easy aggregation of the metal components. Herein, we report a bottom-up preparation strategy to obtain a porous ethynyl-linked conjugated microporous polymer (CMP) precursor containing triazine units and bipyridine, ensuring high N content and coordination with Fe3+. The Fe doped CMP is then carbonization into a Fe, N co-doped nanoporous carbon material (BPCMP-Fe-800), which can be taken as the electrocatalyst in ORR. BPCMP-Fe-800 catalyst exhibits electrocatalytic performance dominated by 4e− transfer mechanism with the onset potential of 0.97 V, half-wave potential of 0.85 V, and higher kinetic current density of 11.3 mA cm−2 (0.8 V). In addition, when applied as cathode electrocatalyst in zinc-air batteries, BPCMP-Fe-800 displays more competitive power density (179.5 mW cm−2) and specific capacity (790.5 mAh g−1) compared with Pt/C. Our study demonstrates a general and facile approach for porous Fe, N co-doped carbon with the potential as alternatives to Pt catalysts for efficient ORR catalytic performances and provides new insights of multi-atom catalysts for other energy conversion related catalytic reactions. |

BPCMP-Fe-800 catalyst exhibits electrocatalytic performance dominated by 4e− transfer mechanism with the onset potential of 0.97 V, half-wave potential of 0.85 V, and higher kinetic current density of 11.3 mA cm−2 (0.8 V). In addition, when applied as cathode electrocatalyst in zinc-air batteries, BPCMP-Fe-800 displays more competitive power density (179.5 mW cm−2) and specific capacity (790.5 mAh g−1) compared with Pt/C. Our study demonstrates a general and facile approach for porous Fe, N co-doped carbon with the potential as alternatives to Pt catalysts for efficient ORR catalytic performances and provides new insights of multi-atom catalysts for other energy conversion related catalytic reactions.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Bipyridine</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Oxygen reduction reaction</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Conjugated microporous polymer</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">Fe</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">N co-doping</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cao, Zuolin</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li, Longyu</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ren, Shijie</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="n">Elsevier Science</subfield><subfield code="a">Zhao, Zhi-Dan ELSEVIER</subfield><subfield code="t">Dynamic patterns of open review process</subfield><subfield code="d">2021</subfield><subfield code="d">an international journal sponsored by the American Carbon Society</subfield><subfield code="g">Amsterdam [u.a.]</subfield><subfield code="w">(DE-627)ELV006580718</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:200</subfield><subfield code="g">year:2022</subfield><subfield code="g">day:5</subfield><subfield code="g">month:11</subfield><subfield code="g">pages:337-346</subfield><subfield code="g">extent:10</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.carbon.2022.08.068</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ELV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OPC-MAT</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">33.25</subfield><subfield code="j">Thermodynamik</subfield><subfield code="j">statistische Physik</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">31.00</subfield><subfield code="j">Mathematik: Allgemeines</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">200</subfield><subfield code="j">2022</subfield><subfield code="b">5</subfield><subfield code="c">1105</subfield><subfield code="h">337-346</subfield><subfield code="g">10</subfield></datafield></record></collection>
