Hydrotalcite from modified combustion method

Abstract

Hydrotalcite-like compounds were successfully synthesized using the modified combustion method from aluminum and magnesium nitrates and potassium carbonate. Glucose was used as fuel. The synthesis temperatures were systematically varied. The resulting hydrotalcites were calcined until lattice destruction and recrystallization in the presence of a carbonate aqueous solution was achieved. The structural modifications were evaluated using X-ray diffraction, SEM, EDX and FTIR.
