Abstract
A method of applying a hierarchical porous ZrO2 includes: 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; adding a zirconium salt to the mixed solution and stirring; heating the mixed solution in an oven to obtain ZrO2, promoting the conversion of the crystal form of ZrO2; calcining ZrO2 at a high temperature to obtain the hierarchical porous ZrO2; mixing the hierarchical porous ZrO2 with a solution containing a lysozyme protein; and absorbing the lysozyme protein to the hierarchical porous ZrO2.
