Abstract

Intercalating anions like Cl- into layered double hydroxides (LDHs) can release pollutants and form poorly structured crystals. This study suggests stearic acid as a sustainable alternative, enhancing crystal quality and reducing environmental impact. LDH-Stearate was synthesized via one-pot stearic acid intercalation and characterized by TGA, XRD, BET, FTIR, and FE-SEM. Results confirmed improved thermal stability, well-organized crystals, and mesoporous characteristics. Stearic acid shows promise for customizing LDH properties for applications in drug delivery, catalysis, and flame retardants, emphasizing the need for further research to optimize intercalation conditions and practical uses.
