High-efficiency electrochemical hydrogen evolution based on the intermetallic Pt2Si compound prepared by magnetron-sputtering

Abstract: An intermetallic Pt2Si compound was prepared by magnetron sputtering, which exhibited higher HER activity than that of Pt in acidic solution.

“…These functions were considered in the selection of the starting compound. In combination with the known activity of Pt and Pt-based intermetallic compounds in the hydrogen evolution reaction (HER), [52,53] this opens an ew strategy in the development of bifunctional electrocatalysts.T hin-film technologies and the design of a( less costly) bulk phase as as upport are avenues for further developing the strategy. Other intermetallic compounds featuring amphoteric nonnoble metals in large fractions are also possible candidates for expanding the material basis of our concept.…”

“…The Pt 2 Si was tested in 0.5 M H 2 SO 4 electrolyte for HER resulting in η -10 of 78 mV and a Tafel slope of 30.5 mV dec -1 . 186 Electrode materials containing Pd have also been a focus of research as it is an interesting substitute for Pt. Although Pd is a noble metal, its price is much lower and shows similar activity to Pt in HER.…”

“…Diese Funktionen wurden bei der Auswahl der Ausgangsverbindung berücksichtigt. In Kombination mit der bekannten Aktivitätv on Platin und Platin-basierten intermetallischen Verbindungen in Wasserstoffentwicklungsreaktionen (HER) [52,53] erçffnet dies eine neue Strategie in der Entwicklung bifunktioneller Elektrokatalysatoren. Dünnschichttechniken und die Auswahl einer (weniger kostspieligen) Massivmaterialphase als Tr äger sind Wege zur Weiterentwicklung der Strategie.A uch andere intermetallische Verbindungen mit amphoteren Nichtedelmetallen in großen Anteilen sind mçgliche Kandidaten füre ine Erweiterung der Materialbasis dieses Konzepts.…”
