Graphical Abstract

Über eine milde Reaktion in Lösung mit nachfolgendem Tempern wurde ein hybrider Elektrokatalysator aus Co_1−xS-Nanopartikeln auf Schichten von reduziertem Graphenoxid (RGO; siehe SEM-Bild) für die Sauerstoffreduktionsreaktion (ORR) hergestellt. Co_1−xS/RGO zeigt die höchste katalytische Leistung aller ORR-Katalysatoren auf Cobaltchalkogenidbasis, wie u. a. Messungen mit einer rotierenden Scheibenelektrode ergaben (siehe Bild; RHE=reversible Wasserstoffelektrode).
