Abstract

The invention discloses a synthesis method of a CeO2 nanobelt. The method comprises the steps of dissolving cerous nitrate and 1,3-phthalic acid into a mixed solvent of absolute ethyl alcohol and water to obtain a 0.02mol / L Ce(NO3)3 solution; putting the mixed solution into a reaction kettle and synthesizing a cerium coordination polymer precursor through a mixed solvent-thermal method; and preparing a quasi one-dimensional CeO2 nanobelt through simple burning. A surfactant does not need to be added, alkali liquor does not need to be added, the influence of the dripping speed of the alkali liquor on the shape of the material is avoided and the synthesis method is simple and efficient.
