Abstract
Solids with photocatalytic properties have been prepared by calcination of hydrocalumite (a sort of layered double hydroxide, LDH) at 750 °C, which had been prepared using an aluminum salt cake as a source. The characterization of the obtained solids was performed by powder X–ray diffraction, FT–infrared spectroscopy, thermal analysis, N2 adsorption–desorption isotherms at −196 °C and electron microscopy. Different crystalline phases were identified depending on the amount of Fe3+ incorporated. The Fe–free photocatalyst showed the best performance under UV light for the photodegradation of ibuprofen.
