제목 Ni nanoparticle decorated reduced graphene oxide sheet catalyst for electrochemical water splitting  
초록 Ni nanoparticle decorated reduced graphene oxide sheets were synthesized by ligand assisted assembly method. As prepared Ni-RGO composite was investigated as catalyst for hydrogen evolution reaction. Immobilization of nickel on graphene oxide surface was found to enhance its catalytic activity. The composite material required low over potential of 128 mV and 197mV to reach current density of 1 mA g-1 and 10 mA g-1 respectively. Tafel analysis showed a low Tafel slope of 67 mV decade-1 suggesting that that reaction follows Volmer-Tafel mechanism. Furthermore catalyst was reused for 100 cycles without appreciable loss in catalytic activity.
