Structural and spectroscopic study of tripeptide/layered double hydroxide hybrids

► Experimental measurements and theoretical computation were used. ► First time used XPS techniques to analyze the relative content in the LDHs' interlayer. ► Reacting temperature affects the intercalation of GSH into LDH interlayer. ► The reaction mechanism of intercalating GSH into LDHs was explained by the IRC.
