NOVELTY - A cobalt molybdate-graphene nano-composite contains 5-50 wt.% graphene. USE - Cobalt molybdate-graphene nano-composite used for electronic device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of cobalt molybdate-graphene nano-composite. Graphite oxide is dispersed in water to obtain oxidized graphite alkene solution, and cobalt salt solution is added and dissolved. Molybdenum salt is added to the obtained mixed solution, stirred, and the pH is adjusted. The resultant mixed solution is added to hydro-thermal reaction kettle, filtered, washed and dried to obtain cobalt molybdate-graphene nano-composite.
