The effect of amines in the synthesis of layered double hydroxides

Layered double hydroxides (LDH) which are one type of layered materials and are also known as anionic clays, are promising layered materials due to some of their interesting properties, such as ease of synthesis, unique structure and high chemical and thermal stability [1]. Layered double hydroxides (LDHs), with nitrate as the charge balancing anion in the interlayer space, were synthesized by precipitation from homogeneous solution containing different amines [e.g., hexamethylenetetraamine (HMTA), diethylenediamine (DEDA), trimethylamine (TMA) and dimethylamine (DMA)]. This study investigates the use of different amines instead of nitrogen atmosphere in synthesis of nitrate containing LDHs.
