有机柱撑粘土的表面酸性、结构特征及层间柱环境研究

In this study, pillared clays were synthesized and characterized using various spectra and surfacial analysis technology. Our results elucidated the microstuctural state, the combination style between pillared oins and clay minerals and the origin of surfacial active sites of pillared and acid-activated clay minerals. It is useful for synthesis, characterization and application of pillared clays.

本项目以矿物界面物理化学为基础理论，采用谱学和表面分析技术，通过对有机柱撑粘土的层间柱和层间表面结构、柱撑后粘土矿物原子局域结构变化等的研究，阐明有机柱撑粘土具有表面酸性的结构本质。本研究将材料化学和矿物学有机地结合起来，能更客观地反映出有机柱撑粘土具有表面酸性的结构本质，并可为新型材料的分子设计和合成提供理论依据。
