Hierarchical porous ZrO2 material, method of preparing the same, and application thereof

Abstract

A method for preparing a hierarchical porous ZrO2 includes the following steps: S1, dissolving a triblock copolymer in an organic solvent to obtain a solution A, dissolving a tannin extract in distilled water to obtain a solution B, mixing the solution A and the solution B and stirring to obtain a mixed solution; S2, adding a zirconium salt to the mixed solution obtained in step S1 and stirring; S3, heating the mixed solution obtained in step S2 in an oven to obtain ZrO2, promoting the conversion of the crystal form of ZrO2; S4, calcining ZrO2 at a high temperature to obtain the hierarchical porous ZrO2.
