New insight into structural transformations of borocarbonitride in oxidative dehydrogenation of propane
Boron-containing compounds have been discovered as a kind of promising metal-free catalysts for oxidative dehydrogenation (ODH) of alkanes. Herein, we provide a simple method to synthesize a series of BCN catalysts with tunable carbon contents. We reveal that incorporating appropriate amounts of car...

| 520 | |a Boron-containing compounds have been discovered as a kind of promising metal-free catalysts for oxidative dehydrogenation (ODH) of alkanes. Herein, we provide a simple method to synthesize a series of BCN catalysts with tunable carbon contents. We reveal that incorporating appropriate amounts of carbon into the hexagonal boron nitride (h-BN) structure can significantly increase the surface area and lead to remarkable enhanced catalytic conversion. The best-performing catalyst shows 82.3% propylene selectivity and 93.8% olefin selectivity at propane conversion of 18.5%. Systematic study indicates that the carbon doping can derive BN with a large number of defective sites, which are prone to form reactive boron-oxygen species during activation. The excess carbon inclusion, however, results in a decreased catalytic conversion, originated from catalyst decomposition and sintering. In situ transmission electron microscopy (TEM) performed under activation and catalytic reaction conditions shows the dynamic process of gas-phase induced structural/compositional transformations, providing direct insights into the origins of catalytic deactivation. | ||

We reveal that incorporating appropriate amounts of carbon into the hexagonal boron nitride (h-BN) structure can significantly increase the surface area and lead to remarkable enhanced catalytic conversion. The best-performing catalyst shows 82.3% propylene selectivity and 93.8% olefin selectivity at propane conversion of 18.5%. Systematic study indicates that the carbon doping can derive BN with a large number of defective sites, which are prone to form reactive boron-oxygen species during activation. The excess carbon inclusion, however, results in a decreased catalytic conversion, originated from catalyst decomposition and sintering. In situ transmission electron microscopy (TEM) performed under activation and catalytic reaction conditions shows the dynamic process of gas-phase induced structural/compositional transformations, providing direct insights into the origins of catalytic deactivation.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">BN catalysts</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Carbon mediating</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">In situ TEM</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Oxidative dehydrogenation of propane</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhang, Xuefei</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yan, Yao</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Huang, Xing</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Xie, Zailai</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">Bai, Yang ELSEVIER</subfield><subfield code="t">Functionalized rGO as covalent crosslinkers for constructing chemically stable polysulfone-based anion exchange membranes with enhanced ion conductivity</subfield><subfield code="d">2018</subfield><subfield code="d">an international journal devoted to catalytic science and its applications</subfield><subfield code="g">Amsterdam [u.a.]</subfield><subfield code="w">(DE-627)ELV001102958</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:628</subfield><subfield code="g">year:2021</subfield><subfield code="g">day:25</subfield><subfield code="g">month:11</subfield><subfield code="g">pages:0</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.apcata.2021.118402</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-OLC-PHA</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">58.11</subfield><subfield code="j">Mechanische Verfahrenstechnik</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">628</subfield><subfield code="j">2021</subfield><subfield code="b">25</subfield><subfield code="c">1125</subfield><subfield code="h">0</subfield></datafield></record></collection>

New insight into structural transformations of borocarbonitride in oxidative dehydrogenation of propane |
| abstract |
Boron-containing compounds have been discovered as a kind of promising metal-free catalysts for oxidative dehydrogenation (ODH) of alkanes. Herein, we provide a simple method to synthesize a series of BCN catalysts with tunable carbon contents. We reveal that incorporating appropriate amounts of carbon into the hexagonal boron nitride (h-BN) structure can significantly increase the surface area and lead to remarkable enhanced catalytic conversion. The best-performing catalyst shows 82.3% propylene selectivity and 93.8% olefin selectivity at propane conversion of 18.5%. Systematic study indicates that the carbon doping can derive BN with a large number of defective sites, which are prone to form reactive boron-oxygen species during activation. The excess carbon inclusion, however, results in a decreased catalytic conversion, originated from catalyst decomposition and sintering. In situ transmission electron microscopy (TEM) performed under activation and catalytic reaction conditions shows the dynamic process of gas-phase induced structural/compositional transformations, providing direct insights into the origins of catalytic deactivation. |
