Synthesis and characterization of nanosized ZnTiO₃doped with reduced graphene oxide (RGO)

Journal of Physics: Conference Series, 2021
AbstractComposite materials based on nanosized zinc titanate (ZnTiO3) doped with reduced graphene oxide (RGO) were obtained by means of ultrasonically assisted precipitation. In these composites, the concentration of RGO nanopartiles was varied from 1 wt.% to 20 wt.%. The ZnTiO3ceramic was produced by sol-gel method.
