Formation of Co3O4 accompanied with GO reduction takes place simultaneously (in situ) upon.-ray exposure carried out at a rate of 5.1 KGy h(-1). Reduction of GO and formation of Co3O4 were confirmed by XRD, Raman and UV-vis spectroscopy. XRD and HRTEM results supports the embedding of nano-crystalline Co3O4 in an amorphous matrix. Relatively larger crystallites of cobalt oxide obtained in the presence of rGO proved to be a decisive supporting material for the directional growth of Co3O4. Electrochemical characterization established the fact that rGO is indeed considered as a proficient medium for electrochemical electron transfer process. Photo-assisted H-2 generation studies using Co3O4 and Co3O4-rGO nano-composite yielded 3 and 30 mu mol h(-1) g(-1) of hydrogen (H-2) generation, respectively, supports the action of rGO as an electron trap.</p>10anano cobalt oxide10aphotocatalytic hydrogen production10aReduced graphene oxide1 aGupta, Bhavana1 aMelvin, Ambrose, A.1 aMatthews, Tom1 aDash, S.1 aTyagi, A., K.  uhttps://library.ncl.res.in/content/facile-gamma-radiolytic-synthesis-synergistic-co3o4-rgo-nanocomposite-direct-use
