Deposition of Co3O4nanoparticles onto exfoliated graphite oxide sheets†
Abstract
A composite of graphite oxide (GO)-supported Co3O4nanoparticles (NPs) was prepared through a facile chemical route. The lamellar GO sheets in this composite were exfoliated and decorated randomly by Co3O4 particles with an average size of 100 nm. The formation route to anchor Co3O4 NPs onto the exfoliated GO sheets was proposed as the intercalation and
