Abstract

original image

Eine Verbindung aus Schichten von kristalliner Rutheniumsäure und Wasser kann so gespalten werden, dass kolloidale Nanoblätter entstehen. Dieses Material zeigt gemischte Leitungseigenschaften: Die kristallinen Nanoblätter tragen zur elektronischen Leitfähigkeit bei, die wässrigen Zwischenschichten leiten dagegen Protonen (siehe Bild). Die große aktive Oberfläche und die hohe spezifische Kapazität sind vielversprechende Voraussetzungen für die Anwendung in elektrochemischen Superkondensatoren.
