“…Nanostructured ceria can be synthesized using various approaches, such as precipitation, hydrothermal, sol-gel, and surfactant-assisted synthesis ( Figure 6) [6,9,38,84]. The common cerium precursors used for synthesis includes cerium ( [87,88], and cerium chloride (CeCl 3 ) [89,90]. Synthetic procedures developed in recent years have allowed the formation of ceria into desirable nanoshapes with well-defined exposed planes.…”
