PtRu nanoparticles supported on p-phenylenediamine-functionalized multiwalled carbon nanotubes: enhanced activity and stability for methanol oxidation

Abstract A facile method was developed for preparation of PtRu nanoparticles/multiwalled carbon nanotubes (MWCNTs) electrocatalysts for methanol oxidation. Starting from pristine MWCNTs, high dispersion of PtRu nanoparticles was directly assembled on the side wall of MWCNTs by using p-phenylenediami...

520			\|a Abstract A facile method was developed for preparation of PtRu nanoparticles/multiwalled carbon nanotubes (MWCNTs) electrocatalysts for methanol oxidation. Starting from pristine MWCNTs, high dispersion of PtRu nanoparticles was directly assembled on the side wall of MWCNTs by using p-phenylenediamine (PPDA) as the inter-linker. FTIR and Raman spectroscopy examinations show that PPDA can be immobilized on pristine MWCNTs by π-π stacking, and the integral structure of MWCNTs was preserved after modification. TEM and XRD investigations show that the face-centered cubic (fcc) Pt structure of PtRu alloy nanoparticles with average diameter 3.5 ± 0.5 nm are uniformly supported on the surface of PPDA-functionalized MWCNTs (PPDA-MWCNTs). The resulting PtRu/PPDA-MWCNTs catalyst exhibits a more negative onset potential (0.15 V) than PtRu/MWCNTs (0.33 V), showing the higher electrocatalytic activity towards methanol oxidation, while its forward peak current density (731.6 $ mAmg^{−1} $ of Pt) is 1.66 times higher than that of PtRu/MWCNTs (440.5 $ mAmg^{−1} $ of Pt). The PtRu/PPDA-MWCNTs catalyst also shows significantly enhanced steady-state current and long-term stability. The smaller size, better dispersion, and higher electrochemical surface area (73.5 $ m^{2} $ $ g^{−1} $) of the PtRu nanoparticles on PPDA-MWCNTs result in superior electrocatalytic performance towards methanol oxidation. This work may provide an efficient method to fabricate MWCNTs-supported superior noble metal catalysts for broad applications in energy systems and sensing devices.

Starting from pristine MWCNTs, high dispersion of PtRu nanoparticles was directly assembled on the side wall of MWCNTs by using p-phenylenediamine (PPDA) as the inter-linker. FTIR and Raman spectroscopy examinations show that PPDA can be immobilized on pristine MWCNTs by π-π stacking, and the integral structure of MWCNTs was preserved after modification. TEM and XRD investigations show that the face-centered cubic (fcc) Pt structure of PtRu alloy nanoparticles with average diameter 3.5 ± 0.5 nm are uniformly supported on the surface of PPDA-functionalized MWCNTs (PPDA-MWCNTs). The resulting PtRu/PPDA-MWCNTs catalyst exhibits a more negative onset potential (0.15 V) than PtRu/MWCNTs (0.33 V), showing the higher electrocatalytic activity towards methanol oxidation, while its forward peak current density (731.6 $ mAmg^{−1} $ of Pt) is 1.66 times higher than that of PtRu/MWCNTs (440.5 $ mAmg^{−1} $ of Pt). The PtRu/PPDA-MWCNTs catalyst also shows significantly enhanced steady-state current and long-term stability. The smaller size, better dispersion, and higher electrochemical surface area (73.5 $ m^{2} $ $ g^{−1} $) of the PtRu nanoparticles on PPDA-MWCNTs result in superior electrocatalytic performance towards methanol oxidation.

Starting from pristine MWCNTs, high dispersion of PtRu nanoparticles was directly assembled on the side wall of MWCNTs by using p-phenylenediamine (PPDA) as the inter-linker. FTIR and Raman spectroscopy examinations show that PPDA can be immobilized on pristine MWCNTs by π-π stacking, and the integral structure of MWCNTs was preserved after modification. TEM and XRD investigations show that the face-centered cubic (fcc) Pt structure of PtRu alloy nanoparticles with average diameter 3.5 ± 0.5 nm are uniformly supported on the surface of PPDA-functionalized MWCNTs (PPDA-MWCNTs). The resulting PtRu/PPDA-MWCNTs catalyst exhibits a more negative onset potential (0.15 V) than PtRu/MWCNTs (0.33 V), showing the higher electrocatalytic activity towards methanol oxidation, while its forward peak current density (731.6 $ mAmg^{−1} $ of Pt) is 1.66 times higher than that of PtRu/MWCNTs (440.5 $ mAmg^{−1} $ of Pt). The PtRu/PPDA-MWCNTs catalyst also shows significantly enhanced steady-state current and long-term stability. The smaller size, better dispersion, and higher electrochemical surface area (73.5 $ m^{2} $ $ g^{−1} $) of the PtRu nanoparticles on PPDA-MWCNTs result in superior electrocatalytic performance towards methanol oxidation. This work may provide an efficient method to fabricate MWCNTs-supported superior noble metal catalysts for broad applications in energy systems and sensing devices.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Anodes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Catalyzes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Electrochemical stabilities</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Electrodes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Fuel cells</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhu, Jiajin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li, Xue</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Xiaoqin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chu, Jia</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Xiong, Shanxin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Ionics</subfield><subfield code="d">Berlin : Springer, 1995</subfield><subfield code="g">25(2018), 1 vom: 11.

abstract	Abstract A facile method was developed for preparation of PtRu nanoparticles/multiwalled carbon nanotubes (MWCNTs) electrocatalysts for methanol oxidation. Starting from pristine MWCNTs, high dispersion of PtRu nanoparticles was directly assembled on the side wall of MWCNTs by using p-phenylenediamine (PPDA) as the inter-linker. FTIR and Raman spectroscopy examinations show that PPDA can be immobilized on pristine MWCNTs by π-π stacking, and the integral structure of MWCNTs was preserved after modification. TEM and XRD investigations show that the face-centered cubic (fcc) Pt structure of PtRu alloy nanoparticles with average diameter 3.5 ± 0.5 nm are uniformly supported on the surface of PPDA-functionalized MWCNTs (PPDA-MWCNTs). The resulting PtRu/PPDA-MWCNTs catalyst exhibits a more negative onset potential (0.15 V) than PtRu/MWCNTs (0.33 V), showing the higher electrocatalytic activity towards methanol oxidation, while its forward peak current density (731.6 $ mAmg^{−1} $ of Pt) is 1.66 times higher than that of PtRu/MWCNTs (440.5 $ mAmg^{−1} $ of Pt). The PtRu/PPDA-MWCNTs catalyst also shows significantly enhanced steady-state current and long-term stability. The smaller size, better dispersion, and higher electrochemical surface area (73.5 $ m^{2} $ $ g^{−1} $) of the PtRu nanoparticles on PPDA-MWCNTs result in superior electrocatalytic performance towards methanol oxidation. This work may provide an efficient method to fabricate MWCNTs-supported superior noble metal catalysts for broad applications in energy systems and sensing devices. © Springer-Verlag GmbH Germany, part of Springer Nature 2018
