Crumpled reduced graphene oxide Balls (CGB) are produced in a High Temperature Reducing Jet (HTRJ) reactor. The key advantage of the HTRJ system over common flame-based aerosol synthesis methods is the separation of flame and product formation zones, which allows synthesis of non-oxide nanomaterials that can be reduced by H2 in the presence of H2O. Thus, CGBs are simultaneously decorated with different transition metal nanoparticles including cobalt (Co), nickel (Ni), iron (Fe), and palladium (Pd). The HTRJ process enables rapid aerosol (gas phase) formation of metal-decorated crumpled reduced graphene oxide Balls (M-CGBs) with relatively high production rates from low-cost metal precursors and graphene oxide (GO) aqueous dispersions. Characterization techniques confirm the decoration of
