摘要:

以表面活性剂十二烷基磺酸钠为辅助模板剂,合成了具有较高稳定性的介孔二氧化锆。 采用TG、XRD、FT-IR以及N2吸附-脱附等测试技术对产物进行了表征。 研究结果表明,以阴离子型表面活性剂为模板合成的二氧化锆前驱体具有层状介孔结构,经过NaOH溶液处理后再经500 ℃煅烧仍能保持其介孔结构,显示了良好的热稳定性。 在表面活性剂脱除后得到双孔分布的孔结构,其孔壁为四方晶相结构。 NaOH对其结构的形成起到了关键作用。

Abstract:

A lamellar mesoporous zirconia with fairly high stability was successfully synthesized using an anionic surfactant as template via a hydrothermal process and characterized by means of TG, XRD, FT-IR and N2 adsorption-desorption. The precursor of zirconia synthesized with the anionic surfactant as template and it as-product treated by NaOH solution and calcination at 500 ℃ both have a lamellar mesoporous structure, which implies their excellent thermal stabilities. The material owns bimodal mesoporous structure and has crystallized pore wall with a pure tetragonal phase after the decomposition of surfactant. It was also found that an alkaline treatment process plays a critical role in forming such material.

Key words: mesoporous zirconia, anionic surfactant, hydrothermal method
