Abstract In this article, a new hierarchical porous zirconia material with adjustable pore size is fabricated by using biomass materials of acacia mangium tannin extract (AMTE) and amphiphilic triblock copolymer poly(ethylene glycol)-blockpoly(propylene glycol)-block-poly(ethylene glycol) (P123) as a dual-template for the first time. All the raw materials we used are non-toxic and the synthesis process is relatively simple, low-cost, eco-friendly, and reproducible, which is suitable for large-scale production. A serious characterization of SEM, N2 sorption isotherm, and Mercury intrusion porosimetry indicate that hierarchical porous ZrO2 combining abundant mesopores and macropores was synthesized successfully by P123 and AMTE as a dual template. Intriguing, dual-templated ZrO2 with hierarchical porosity has an advantage over single-templated samples in protein adsorption, especially for the large-sized proteins. Furthermore, the real sample test shows the synthesized material with a multidimensional porous structure displays the application potential in practical protein wastewater.

由金合欢单宁提取物和两亲性三嵌段共聚物双模板化的分层多孔二氧化锆

摘要 本文以金合欢单宁提取物（AMTE）和两亲性三嵌段共聚物聚（乙二醇）-嵌段聚（丙二醇）-嵌段-聚（乙烯）为原料，制备了一种孔径可调的分级多孔氧化锆材料。乙二醇）（P123）首次作为双模板。我们使用的所有原料都是无毒的，合成过程相对简单，成本低，环保，可重复，适合规模化生产。SEM、N2 吸附等温线和压汞孔隙率的严格表征表明，P123 和 AMTE 作为双模板成功合成了结合丰富中孔和大孔的分层多孔 ZrO2。耐人寻味，具有分级孔隙率的双模板 ZrO2 在蛋白质吸附方面优于单模板样品，特别是对于大尺寸蛋白质。此外，实际样品测试表明，具有多维多孔结构的合成材料在实际蛋白质废水中显示出应用潜力。
