Electrochemical hydrogen storage properties of NiAl_2O_4 NiO nanostructures using TiO_2, SiO_2 and graphene by auto-combustion method using green tea extract


AbstractNiAl2O4/NiO nanostructures were synthesized via an auto-combustion method using green tea extract. TiO2, SiO2, and graphene were used in order to enhance the electrochemical hydrogen storage performance of NiAl2O4. The structural analysis of host texture confirmed the formation of NiO alongside with NiAl2O4. Furthermore, the formation of nanocomposites and distribution of the additives on the surface of NiAl2O4/NiO nanostructures were affirmed by XRD and EDS spectra. The morphological analyses were displayed the nanoscale formation of the particles. Interestingly, the electrochemical hydrogen storage of the nanocomposites indicated that upon addition of TiO2, SiO2and graphene, the discharge capacity enhanced as compare to the host material. The maximum discharge capacities of NiAl2O4/NiO and its respective nanocomposites containing SiO2, graphene, and TiO2were observed at 850, 2000, 2750 and 3000 mA h/g, respectively.Graphical abstractDisplay OmittedHighlightsNiAl2O4/NiO nanocomposite has been prepared by using green tea extract.Electrochemical hydrogen storage of NiAl2O4/NiO was studied, for the first time.Discharge capacity of NiAl2O4/NiO increased by using TiO2, SiO2and graphene.The specific surface area rises due to second phase of TiO2, SiO2and graphene.......
