Synthesis and characterization of mesoporous alumina with high surface area as support for catalytic application

Mesoporous-alumina with high specific surface area was successfully synthesized based on precipitation method. The structural and chemical properties were studied by N2 adsorption– desorption, X-ray diffraction (XRD) and scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS). The mesoporous Al2O3 support had large surface area and high thermal stability. The effect of calcination temperature on alumina surface area was investigated. When the calcination temperature was decreased the surface area increased from82.1 m2/g to 222.05 m2/g.
