Zinc silicate (Zn2SiO4) nanoparticles were synthesized via sonochemical route and polyvinylpyrrolidone (PVP) as a capping agent. In order to achieve optimized morphology and size of nanostructures, experiment was carried out in various conditions. Afterwards, optimum Zn2SiO4 nanoparticle was used for preparing oxide-graphene nanocomposite. Zn2SiO4-graphene nanocomposite was prepared by pre-graphenization method. Finally, electrochemical hydrogen storage capacity of Zn2SiO4 nanoparticle and Zn2SiO4-graphene nanocomposite were investigated and compared. Obtained results represent that Zn2SiO4-graphene nanocomposites have higher electrochemical hydrogen storage capacity than Zn2SiO4 nanoparticles. It was found that the synergistic effect between Zn2SiO4 nanoparticles and graphene sheets can improve the electrochemical performance of this hybrid composite electrode.
