Development of composite anode electrocatalyst for direct methanol fuel cells
Abstract Different effects of support hydrophilicity and metal-oxide on the performance of Pt-based catalysts were investigated with the aim of improving the mass activities toward methanol electrooxidation. Both potentiodynamic and potentiostatic measurements revealed that improved surface hydrophi...

| 520 | |a Abstract Different effects of support hydrophilicity and metal-oxide on the performance of Pt-based catalysts were investigated with the aim of improving the mass activities toward methanol electrooxidation. Both potentiodynamic and potentiostatic measurements revealed that improved surface hydrophilicity of multi-wall carbon nanotubes (MWCNTs) could promote the dispersion of Pt nanoparticles and, consequently, promote the Pt utilization and reduce the polarization in methanol electrooxidation. In addition, $ WO_{3} $ was shown to play a supportive role in enhancing catalytic activity. The interaction between Pt and $ WO_{3} $ was examined by CO-stripping and CO oxidation transient experiments. The results suggested that the activity and the kinetics of monolayer $ CO_{ads} $ electrooxidation of Pt nanoparticles are enhanced by the adjacent $ WO_{3} $ via a bifunctional mechanism, which accounts for improved activity in methanol electrooxidation. | ||

Both potentiodynamic and potentiostatic measurements revealed that improved surface hydrophilicity of multi-wall carbon nanotubes (MWCNTs) could promote the dispersion of Pt nanoparticles and, consequently, promote the Pt utilization and reduce the polarization in methanol electrooxidation. In addition, $ WO_{3} $ was shown to play a supportive role in enhancing catalytic activity. The interaction between Pt and $ WO_{3} $ was examined by CO-stripping and CO oxidation transient experiments. The results suggested that the activity and the kinetics of monolayer $ CO_{ads} $ electrooxidation of Pt nanoparticles are enhanced by the adjacent $ WO_{3} $ via a bifunctional mechanism, which accounts for improved activity in methanol electrooxidation.

Both potentiodynamic and potentiostatic measurements revealed that improved surface hydrophilicity of multi-wall carbon nanotubes (MWCNTs) could promote the dispersion of Pt nanoparticles and, consequently, promote the Pt utilization and reduce the polarization in methanol electrooxidation. In addition, $ WO_{3} $ was shown to play a supportive role in enhancing catalytic activity. The interaction between Pt and $ WO_{3} $ was examined by CO-stripping and CO oxidation transient experiments. The results suggested that the activity and the kinetics of monolayer $ CO_{ads} $ electrooxidation of Pt nanoparticles are enhanced by the adjacent $ WO_{3} $ via a bifunctional mechanism, which accounts for improved activity in methanol electrooxidation.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Methanol electrooxidation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">CO electrooxidation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Surface hydrophilicity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">WO</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Direct methanol fuel cells</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Qiu, Xinping</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhao, Long</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chen, Liquan</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhu, Wentao</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of applied electrochemistry</subfield><subfield code="d">Dordrecht [u.a.] : Springer Science + Business Media B.V, 1971</subfield><subfield code="g">39(2009), 10 vom: 09.

Development of composite anode electrocatalyst for direct methanol fuel cells |
| abstract |
Abstract Different effects of support hydrophilicity and metal-oxide on the performance of Pt-based catalysts were investigated with the aim of improving the mass activities toward methanol electrooxidation. Both potentiodynamic and potentiostatic measurements revealed that improved surface hydrophilicity of multi-wall carbon nanotubes (MWCNTs) could promote the dispersion of Pt nanoparticles and, consequently, promote the Pt utilization and reduce the polarization in methanol electrooxidation. In addition, $ WO_{3} $ was shown to play a supportive role in enhancing catalytic activity. The interaction between Pt and $ WO_{3} $ was examined by CO-stripping and CO oxidation transient experiments. The results suggested that the activity and the kinetics of monolayer $ CO_{ads} $ electrooxidation of Pt nanoparticles are enhanced by the adjacent $ WO_{3} $ via a bifunctional mechanism, which accounts for improved activity in methanol electrooxidation. |
