Abstract Nano-sized plate-like alumina is an important inorganic material in catalytic, ceramic and electronic applications due to its unique two-dimensional structure and properties, while its facile synthesis is still under investigation. In this work, nano-sized alumina plate was synthesized by solution combustion method with glycine and polyvinyl alcohol as composite fuels for the first time. The calcination temperature during solution combustion process was optimized as confirmed by XRD, FT-IR, TG-DSC, Raman, 27Al MAS NMR, SEM, TEM, and N2 physisorbtion. Obtained alumina displayed special nano-sized plate morphology and porous structure. It was further adopted as support for cobalt acetate and used as catalyst for selective oxidation of cyclohexane. This work develops a facile approach to synthesize two-dimensional plate-like alumina for catalytic application.

溶液燃烧法合成纳米板状氧化铝

摘要 纳米级板状氧化铝由于其独特的二维结构和性能而成为催化、陶瓷和电子应用中的重要无机材料，但其简便的合成仍在研究中。本工作首次以甘氨酸和聚乙烯醇为复合燃料，采用溶液燃烧法合成了纳米氧化铝板。通过 XRD、FT-IR、TG-DSC、拉曼、27Al MAS NMR、SEM、TEM 和 N2 物理吸附证实，溶液燃烧过程中的煅烧温度得到优化。获得的氧化铝显示出特殊的纳米级板状形态和多孔结构。进一步用作乙酸钴的载体，用作环己烷选择性氧化的催化剂。
