Abstract

Graphene oxide (GO) is reduced spontaneously when palladium nanoparticles are decorated on the surface. The oxygen functional groups at the GO surface near the nanoparticles are absorbed to the palladium to produce palladium oxide interlayer. Palladium therefore grows on GO with preferred orientations, resulting in unique microstructural and electrical properties.
