Abstract

original image

Gemeinsam zum Erfolg: Mit einer Funktionseinheit aus mehrwandigen Kohlenstoffnanoröhren, auf denen ein Rutheniumkatalysator immobilisiert ist, wurde Wasser gespalten (siehe Bild; ITO=Indiumzinnoxid). Die Elektrode zeigte eine hervorragende elektrokatalytische Aktivität bei der Oxidation von Wasser mit hoher Stromdichte und einem niedrigen Überpotential, was ein Fortschritt bei der Entwicklung künstlicher Photosynthesesysteme ist.
