Enhancing electron density, electrochemical, and dielectric properties of nanohybrid materials for advanced photocatalytic antifouling and energy storage

Abstract

The electron density, electrochemical, and dielectric properties of the promising GO@TiO2.ZnO.Ag hybrid nanomaterial (HNM) (Silver nanoparticles (Ag NPs), Zinc oxide (ZnO NPs), and Titanium dioxide (TiO2NPs)) which incorporated on graphene oxide (GO) have been investigated and studied for antifouling materials and energy storage applications. The photocatalytic process of this promising HNM was disclosed and evidenced by the removal of mixed organic pollutions (Methyl orange (MO), Methylene blue (MB), and Imidacloprid pesticide) by quenching of absorption band of mixed pollution compounds under visible light. The electrochemical properties of HNM were measured by cyclic voltammetry analysis, also the dielectric permittivity (ε′) and dielectric loss (ε″) and electric conductivity (σac) for GO@Ag, GO@ZnO, GO@TiO2, GO@TiO2.ZnO, and GO@TiO2.ZnO.Ag HNM were investigated with different frequencies. The dielectric properties showed increasing in dielectric permittivity values that due to the high electron transfer and small size of metal oxides, also the role of the graphene oxide surface. The results confirm that HNM is a promising candidate to use in energy storage, electronics applications, and antifouling materials.
