| Popis: | A Co-Mo nano-composite material, Co2(P2O6) 12H2O. CoMo4O13 2H2O. (C3H4N2)35 has been synthesized and characterized by employing X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD). By using these techniques, the elemental composition of the composite material has been established. By means of differential scanning calorimetry (DSC), in O2 atmosphere, two cycles of thermal studies have been carried on the material to determine its thermal behaviour, (i) from 301.687 K to 735.742 K (heating) and (ii) from 735.733 K to 303.0975 K (cooling). The composite material exhibited predominant exothermic property with the specific heat capacity (Cp) of –52.72 J/kg.K and enthalpy of fusion (exothermic), –44.59 J/g observed at 693.53 K. Also, it exhibited endothermic property from 301.641 K to 361.835 K with Cp of –17.013 J/g.K. Hence this Co-Mo nano-composite can be utilized as thermal energy storage material from 301.641 K to 361.835 K (heating) and heat dissipation material from 361.995 K to 735.742 K. |
