Abstract

original image

Robuste Elektrokatalysatoren für die H2-Freisetzung und -Aufnahme entstehen durch Funktionalisierung mehrwandiger Kohlenstoffnanoröhren mit molekularen Komplexen über π-Stapelung. Die edelmetallfreien Nanomaterialien haben Vorteile gegenüber herkömmlichen Platinkatalysatoren, weil sie kompatibel mit den Arbeitsbedingungen in Protonenaustauschmembran-Systemen und unempfindlich gegen CO sind.
