Graphical Abstract

Empfindliche Schwämme: Schwammartiges Titandioxid (NST) wurde zum Aufbau eines Bauelement-Prototyps für den empfindlichen Nachweis von Wasserstoff genutzt. Für NST ergeben sich aussichtsreiche Anwendungen in Multisensorsystemen wie elektronischen Nasen und Zungen, und dreidimensional vernetzte nanostrukturierte Metalloxide sind vielversprechende Materialien für empfindliche Sensoren. Das Bild zeigt eine SEM-Aufnahme von aus einem 500 nm dicken Ti-Film gebildetem NST.
