Cobalt sulfide materials have attracted enormous interest as low‐cost alternatives to noble‐metal catalysts capable of catalyzing both oxygen reduction and evolution reactions. Although recent advances been achieved in the development various cobalt composites expedite their reaction properties, improve poor (OER) activity is still challenging, which significantly limits utilization. Here, synthesis Fe 3 O 4 ‐decorated Co 9 S 8 nanoparticles situ grown on a reduced graphene oxide surface (Fe...
Graphene, which possesses unique nanostructure and excellent properties, is considered a low cost alternative to carbon nanotubes in nanocomposites.
