Abstract:This study systematically examines the effects of diphenylphosphinic acid (DPPA) and sarcosine (SAR) intercalation into magnesium aluminum lanthanum hydrotalcite (LDHs) on its structure and thermal stability. Using charge distribution, structural optimization, energy calculations, XRD, FTIR, TEM, and thermal stability tests, the study reveals that DPPA anions, with higher negative charge density, increase the interlayer spacing to 6.08 Å and exhibit a binding energy of −0.7624 eV. SAR anions, with a thinner in… Show more
