Nanoporous gold obtained from a metallic glass precursor used as substrate for surface-enhanced Raman scattering
Nanoporous gold (NPG) has been synthesized by electrochemical de-alloying a new precursor, amorphous Au 30 Cu 38 Ag 7 Pd 5 Si 20 (at.%), starting from melt-spun ribbons. Ligaments ranging from 75 to 210 nm depending on the de-alloying time were obtained. Analytical and electrochemical evidence showe...

520 | |a Nanoporous gold (NPG) has been synthesized by electrochemical de-alloying a new precursor, amorphous Au 30 Cu 38 Ag 7 Pd 5 Si 20 (at.%), starting from melt-spun ribbons. Ligaments ranging from 75 to 210 nm depending on the de-alloying time were obtained. Analytical and electrochemical evidence showed the ligaments contain residual Cu, Ag and Pd. Surface-enhanced Raman scattering from the NPG was investigated using pyridine and 4,4′-bi-pyridine as probe molecules. It was found that the activity is at maximum when the ribbon is fully de-alloyed although the ligaments then have a larger size. The enhancement is attributed to the small size of crystals in the ligaments, to their morphology and to trapped atoms. | ||

Surface-enhanced Raman scattering from the NPG was investigated using pyridine and 4,4′-bi-pyridine as probe molecules. It was found that the activity is at maximum when the ribbon is fully de-alloyed although the ligaments then have a larger size. The enhancement is attributed to the small size of crystals in the ligaments, to their morphology and to trapped atoms.</subfield></datafield><datafield tag="540" ind1=" " ind2=" "><subfield code="a">Nutzungsrecht: © 2015 Taylor & Francis 2015</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">amorphous alloys</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Raman spectroscopy</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">melt spinning</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">nanograined structures</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">de-alloying</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">porous metals</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">SERS</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Paschalidou, E.M</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Rizzi, P</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bordiga, S</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Battezzati, L</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Philosophical magazine.

Nanoporous gold obtained from a metallic glass precursor used as substrate for surface-enhanced Raman scattering |
abstract |
Nanoporous gold (NPG) has been synthesized by electrochemical de-alloying a new precursor, amorphous Au 30 Cu 38 Ag 7 Pd 5 Si 20 (at.%), starting from melt-spun ribbons. Ligaments ranging from 75 to 210 nm depending on the de-alloying time were obtained. Analytical and electrochemical evidence showed the ligaments contain residual Cu, Ag and Pd. Surface-enhanced Raman scattering from the NPG was investigated using pyridine and 4,4′-bi-pyridine as probe molecules. It was found that the activity is at maximum when the ribbon is fully de-alloyed although the ligaments then have a larger size. The enhancement is attributed to the small size of crystals in the ligaments, to their morphology and to trapped atoms. |
