摘要: Abstract We developed an environmentally friendly, one-pot strategy toward preparation of Ni nanoparticles-decorated reduced graphene oxide (Ni-RGO) hybrids, through the use ethylene glycol as both solvent and reducing agent under solvothermal conditions. Several analytical techniques were used to characterize resulting Ni-RGO which showed that monodispersed nanoparticles with average diameter 8 nm uniformly anchored onto RGO sheets. Furthermore, taking advantage synergetic effects between supported sheets, hybrids exhibited a better catalytic activity than pure NPs for reduction 4-nitrophenol 4-aminophenol sodium borohydride, kinetic reaction rate being over 2.5 times NPs.
