Bioinspired graphene-based metal oxide nanocomposites for photocatalytic and electrochemical performances: an updated review

“…Also, Youssry et al synthesized TrGO/Ni NCs using the thermal method using nickel foam (NF) as a substrate under the inert atmosphere of nitrogen gas. 111 The as-synthesized TrGO/Ni electrode achieved a very high specic capacitance of 617 f g −1 at a scan rate of 2 mV s −1 . The TrGO/Ni NCs exhibited long-term stability over 2000 cycles at a scan rate of 50 mV s −1 with a capacitance retention of 90.2%.…”

Zn1−xCoxMn1−xFexCrO4 ferrichromate: an efficient material for high performance supercapacitor applications

“…To remove the limitation of energy density, researchers are working extensively throughout the world. 5,6 Recently, researchers are working very hard to graft advanced materials, such as iron oxide homogeneously dispersed on reduced graphene oxide, 7 grafting of polythiophene on graphene oxide sheets, 8 graphene-TiO 2 nanostructure, 9 and reduced graphene oxide-embedded Ni nanoparticles 10 for high performance supercapacitor electrodes for energy storage applications. Further, carbon-based electrodes, 11 Co-Ni layered double hydroxide nanosheets on nickel foam, 12 and carbon nanotubes to produce graphene nanoribbons by microwave radiation 13 were grafted, and the capacitance of the supercapacitor electrodes has increased to a great extent.…”
