Preparation of graphene nanocomposites from aqueous silver nitrate using graphene oxide’s peroxidase-like and carbocatalytic properties

The present study evaluates the role of graphene oxide’s (GO’s) peroxidase-like and inherent/carbocatalytic properties in oxidising silver nitrate (AgNO 3 ) to create graphene nanocomposites with silver nanoparticles (GO/Ag nanocomposite). Activation of peroxidase-like catalytic function of GO required hydrogen peroxide (H 2 O 2 ) and ammonia (NH 3 ) in pH 4.0 disodium hydrogen phosphate (Na 2 HPO 4 ). Carbocatalytic abilities of GO were...
