Basal distance, water loss, TGA residue, and quantity of active molecules for modified LDHs.

Modified LDH	Basal Distance 1 (nm)	Water 2 (wt. %)	TGA Residue (wt. %)	Active Molecule Content 3 (wt. %)
LDH-RA	2.26	5.5	29.0	37
LDH-GA	2.85	10.7	35.0	45
LDH-DS/RA	2.52	8.0	33.1	13
LDH-DS/GA	2.85	7.7	44.3	13

¹ The basal distance of LDH-NO₃ is 0.89 nm [53] and the basal distance of LDH-DS is 2.52 nm [52]. ² The quantity of water (adsorbed and co-intercalated) is given as a percentage by weight of the hybrid, and it has been calculated as the TGA weight loss between 30 and 150–200 °C. ³ The amount of active molecule (RA or GA anions) has been evaluated via UV-vis spectroscopy by dissolving a known amount of modified LDH in concentrated HCl solution.
