Here we report a facile yet versatile strategy for synthetic HCNFs assembly structures (Sn-HCNFs) from Sn-based metal-organic framework (Sn-MOF) via an ethanol flame method (EFM) in atmospheric environment. As Sn-MOF is burned in ethanol flame, HCNFs grow on the surface of Sn-MOF progressively, forming an assembly structure with SnO2 core and HCNFs-forest shell. The process of Sn-HCNFs formation is also investigated by a series of experiments, which demonstrate that, in ethanol flame, Sn-MOF is first converted to SnO2, and then SnO2 catalyzes the formation of Sn-HCNFs. Furthermore, our strategy can also be extended to the preparation of various MOFs-based HCNFs and carbon nanotubes (CNTs)/carbon nanofibers (CNFs) assembly architectures. By electrochemical tests, Sn-HCNFs as electrode materials in supercapacitors exhibit superior electrochemical performances than pure HCNFs. The supercapacitors with the Sn-HCNFs electrode can remain the energy density of 21.67 Wh kg−1 at a very high-power density of 5000 W kg−1. Our strategy provides an alternative route to acquire various HCNFs or CNTs/CNFs assembly structures conveniently and will stimulate further researches on preparation and applications of them. | ||

Helical carbon nanofibers (HCNFs) assembly structure possesses huge development prospects in sorts of applications. Here we report a facile yet versatile strategy for synthetic HCNFs assembly structures (Sn-HCNFs) from Sn-based metal-organic framework (Sn-MOF) via an ethanol flame method (EFM) in atmospheric environment. As Sn-MOF is burned in ethanol flame, HCNFs grow on the surface of Sn-MOF progressively, forming an assembly structure with SnO2 core and HCNFs-forest shell. The process of Sn-HCNFs formation is also investigated by a series of experiments, which demonstrate that, in ethanol flame, Sn-MOF is first converted to SnO2, and then SnO2 catalyzes the formation of Sn-HCNFs. Furthermore, our strategy can also be extended to the preparation of various MOFs-based HCNFs and carbon nanotubes (CNTs)/carbon nanofibers (CNFs) assembly architectures. By electrochemical tests, Sn-HCNFs as electrode materials in supercapacitors exhibit superior electrochemical performances than pure HCNFs. The supercapacitors with the Sn-HCNFs electrode can remain the energy density of 21.67 Wh kg−1 at a very high-power density of 5000 W kg−1. Our strategy provides an alternative route to acquire various HCNFs or CNTs/CNFs assembly structures conveniently and will stimulate further researches on preparation and applications of them. |

By electrochemical tests, Sn-HCNFs as electrode materials in supercapacitors exhibit superior electrochemical performances than pure HCNFs. The supercapacitors with the Sn-HCNFs electrode can remain the energy density of 21.67 Wh kg−1 at a very high-power density of 5000 W kg−1. Our strategy provides an alternative route to acquire various HCNFs or CNTs/CNFs assembly structures conveniently and will stimulate further researches on preparation and applications of them.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Helical carbon nanofibers</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Assembly structure</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Supercapacitors</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Metal-organic frameworks</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Ethanol flame method</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fu, Qingshan</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chen, Xuedan</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yu, Zuxiao</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jin, Yongzhong</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Naiqiang</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Sheng, Yuping</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Xiao, Lili</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chen, Jian</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="n">Elsevier</subfield><subfield code="a">Xiao, Hong ELSEVIER</subfield><subfield code="t">Numerical modeling of wave–current forces acting on horizontal cylinder of marine structures by VOF method</subfield><subfield code="d">2013</subfield><subfield code="d">the international journal on the science and technology of electrochemical energy systems</subfield><subfield code="g">New York, NY [u.a.]</subfield><subfield code="w">(DE-627)ELV00098745X</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:521</subfield><subfield code="g">year:2022</subfield><subfield code="g">day:15</subfield><subfield code="g">month:02</subfield><subfield code="g">pages:0</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.jpowsour.2021.230908</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="936" ind1="b" ind2="k"><subfield code="a">50.92</subfield><subfield code="j">Meerestechnik</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">521</subfield><subfield code="j">2022</subfield><subfield code="b">15</subfield><subfield code="c">0215</subfield><subfield code="h">0</subfield></datafield></record></collection>
