Abstract

original image

Starke Sterne: Verzweigte, konkave, dimetallische Au/Pd-Nanokristalle (siehe Bild) wurden in hoher Ausbeute durch keimvermittelte Coreduktion von Au- und Pd-Metallvorstufen in wässriger Lösung bei Raumtemperatur synthetisiert. Die Verzweigungen sind konkav und haben hochindizierte Facetten auf ihren Oberflächen. Diese Nanokristalle zeigen überlegene elektrokatalytische Aktivität für die Oxidation von Ethanol sowie einen hocheffizienten SERS-Effekt.
