【Synthesis and Characterization of Methanesulfonate and Ethanesulfonate Intercalated Lithium Aluminum LDHs】

Layered double hydroxides (LDHs) consist of alternate positively charged mixed metal hydroxide layers and negatively charged interlayer anions. The successful synthesis of Li-Al-LDHs with intercalated methanesulfonate and ethanesulfonate anions as well as the possible interlayer structure as a function of the temperature is reported.
