Intercalation of mercaptocarboxylic acid into layered double hydroxide accompanied with oxidation of mercapto group
The intercalation of mercaptocarboxylic acids into magnesium-aluminum layered double hydroxide (LDH) was accompanied with the oxidation of mercapto groups in aqueous solution as evidenced by C-13 solid-state NMR and Raman scattering measurements. The layers of LDH were bridged by two carboxylic groups of the corresponding disulfide, which was formed by the oxidation of mercaptocarboxylic acids.
