Resumé

This work aimed to study the synthesis of Mg/Al layered double hydroxides (LDH) from aluminum residues. LDH was produced by co-precipitation and hydrothermal methods using Al(OH)₃ synthesized from aluminum residue. It was possible to confirm the formation of LDH, with an increase in crystallinity for the hydrothermal synthesis. The FTIR indicates no influence regarding the Al(OH)₃ origin (synthesized or commercial). N₂ adsorption/desorption isotherms indicate a mesoporous structure with non-rigid aggregates of plate-shaped particles creating slit pores of varying shapes and sizes. The synthesized materials presented surface area ranging from 27.66 to 96.08 m²/g and pore diameter between 20 and 500 Å. Finally, it can be affirmed that LDHs were satisfactorily synthesized using aluminum residue as a source of aluminum hydroxide.
