Characterization The SEM image of Figure 3a shows that ZnO-TiO2 is composed of ZnO Verdiperstat web nanorods and TiO2 nanoparticles. ZnO nanorods are dispersed inside the surrounding atmosphere. TiO2 nanoparticles are compact in size and randomly stacked with each other. Figure 3b shows the SEM image of graphene oxide. It could be observed that graphene oxide is layered, related to a thin film. It has quite clear folds. The SEM image in Figure 3c is ZnO-TiO2 -rGO ternary nano material. ZnO nanorods and TiO2 nanoparticles are wrapped by graphene film. In addition, it can be seen that the size of TiO2 nanoparticles steadily increases and becomes naturally spherical. It indicated that within the composite method of ZnO-TiO2 -rGO ternaryChemosensors 2021, 9,TiO2 nanoparticles. ZnO nanorods are dispersed within the surrounding environment. TiO2 nanoparticles are tiny in size and randomly stacked with each other. Figure 3b shows the SEM image of graphene oxide. It might be noticed that graphene oxide is layered, comparable to a thin film. It has incredibly apparent folds. The SEM image in Figure 3c is ZnO-TiO2-rGO ternary nano material. ZnO nanorods and TiO2 nanoparticles are wrapped by graphene film. In 5addiof 12 tion, it may be noticed that the size of TiO2 nanoparticles progressively increases and becomes certainly spherical. It indicated that in the composite course of action of ZnO-TiO2-rGO ternary nanomaterials, the formation of ZnO nanorods and TiO2 nanoparticles steadily modifications nanomaterials, the formation of ZnO nanorods and TiO2 nanoparticles progressively adjustments as a result of the existence of graphene. Figure 3d shows the elemental contents corresponding resulting from the existence of graphene. Figure 3d shows the elemental contents corresponding to for the EDS plots. It demonstrates that the ternary nanomaterial ZnO-TiO2-rGO adequately the EDS plots. It demonstrates that the ternary nanomaterial ZnO-TiO2 -rGO adequately consists of components C, O, Ti, and Zn without having the interference of other clutter elements. The includes elements C, O, Ti, and Zn with out the interference of other clutter components. The percentages of elemental C, O, Ti, and Zn contents are listed in Table 1. percentages of elemental C, O, Ti, and Zn contents are listed in Table 1.abb1022crGOd1Figure 3.
