Post synthesis treatment of Layered Double Hydroxides (LDHs) with aqueous immiscible solvents (AIM solvents) yields highly dispersible, high surface area materials (up to 377 m² g⁻¹). The effect of solvent functional groups and structure, initial LDH particle morphology along with parameters such as dispersion time, and solvent recycling properties of AIM-LDHs are explored. The interactions between solvents and LDHs via hydrogen bonding are investigated using high field rapid magic angle spinning (MAS) solid state nuclear magnetic resonance spectroscopy (SSNMR). The strength of the hydrogen bonding interactions that a given solvent can offer appears a crucial factor for the effectiveness of the treatment.

不混溶的层状双氢氧化物水溶液– AIM-LDHs †

用水性不混溶溶剂（AIM溶剂）对层状双氢氧化物（LDH）进行后合成处理，可得到高度可分散的高表面积材料（最大377 m ² g ^-1）。探索了溶剂官能团和结构，初始LDH颗粒形态以及AIM-LDHs的参数（例如分散时间）和溶剂循环特性的影响。使用高场快速魔术角旋转（MAS）固态核磁共振波谱（SSNMR）研究了溶剂与LDHs通过氢键之间的相互作用。给定溶剂可以提供的氢键相互作用的强度似乎是处理效果的关键因素。
