An SEM analysis was done for the electrode material to indicate whether the nano-synthesization and fe dopant gave the desired outcome of oxygen vacancies and increased surface area. The SEM pictures showcased in Figure indicate several things regarding the efficacy and optimacy of the entire project. Images 1A and 1E represent the original or normal MnO2. It shows how clustered and bunched up the MnO2 truly is. There are hardly any gaps, and the network inside is tightly bound. It is almost sponge-like and has very few intricacies. The second set of images, which consists of 2A and 2E, is the doped/synthesized set of images. These images indicate the Fe that has been doped and the hydrogen bonds that have been weakened to create oxygen vacancies. It also represents how widely spread out each of the MnO2 particles is, something this project had aimed to do. The intrinsic properties of the Fe are also clearly present in the SEM pictures. The pictures are progressively getting into a larger scope to give a more comparative analysis. As seen from the second set of images, the surface area has also tremendously risen with larger structures. The images also validate the engineering goal and the project's expected outcome. First, they establish that the Fe dopant successfully created oxygen vacancies. Second, they vali-date the fact that the surface area increased as a result of the nano synthesization. Lastly, they prove that the morphology of the MnO2 has drastically changed with the sol-gel process. These images also show that the nanorods have been successfully formed.
