In this paper, mesoporous alumina with different pore sizes and wall crystalline structures was synthesized at calcination temperatures over 550 °C. The characterization of the samples calcined at 550, 800, 1100, and 1300 °C, respectively, was performed using TEM, XRD, FTIR, TG/DTA, and N 2 adsorption/desorption techniques. The correlation between pore size and wall crystalline structure on calcination temperature was systematically investigated. XRD results of as-synthesized mesostructured alumina (A) and MA after calcination at 550 °C (B), 800 °C (C), 1100 °C (D), and 1300 °C (E) confirm the formation of MA with different crystalline structures.
