In the present work, hydrotalcite containing 5 mol% iron III in co-substitution to the aluminum was prepared by precipitation process and compared with no co-substituted sample along the temperature of calcination at 100 and 500 ºC for 4 hours. The calcined samples were characterized by simultaneous TG/DTA, X-ray Diffraction and nitrogen adsorption-desorption techniques. The iron (III) insertion showed positive results in order to provide more stable structure against high temperatures of calcination, which was observed by lesser structural decomposition of rhombohedral hydrotalcite and a more mesoporous structure.26-31engHydrotalcitePorosityPrecipitation HydroxidesThermal AnalysisTrabalho apresentado em evento10.4028/www.scientific.net/MSF.930.26Acesso aberto2-s2.0-85055085283
