description	The invention discloses a mesoporous cerium oxide nano-material and a preparation method thereof. The preparation method comprises the following steps of: on the basis of using a non-ionic surfactant as a template agent, using an organic silicon source and an organic high-molecular polymer as an organic precursor, using an inorganic cerium source as an inorganic precursor, inducing the four constituents to be co-assembled via evaporation to form an organic-inorganic compound, and then carbonizing in a high-temperature nitrogen atmosphere to form a mesoporous silica/carbon/cerium oxide compound; further oxidizing in air to form a mesoporous silica/cerium oxide compound; finally removing silica via alkaline solution treatment, thereby obtaining the mesoporous cerium oxide nano-material with an ordered pore structure, high heat stability, high specific surface area and high pore volume, wherein the specific surface area achieves 195-209 m /g, the pore diameter achieves 3.2-3.7 nm, and the pore volume achieves 0.
