The formaldehyde-assisted hydrothermal system is used to synthesize CeO2 nanorods by using precursor like cerium
chloride. Concentration of precursors and hydrothermal temperature affects the morphologies of these one-dimensional (1D)
CeO2 Nanomaterial’s. This is achieved to control the reaction degree of Cannizzaro disproportionation tuned by Na/Ce molar
ratio.
