Title

INFLUENCE OF SYNTHESIS PARAMETERS ON THE PROPERTIES OF NANOSTRUCTURED γ-ALUMINA USING PLACKETT-BURMAN EXPERIMENTAL DESIGN

Pages

  386-397

Abstract

 MESOPOROUS NANOSTRUCTUREd g-Al2O3 powders were synthesized through multi- step precipitation procedures using the PH-SWING technique. Structural and morphological characteristics in addition to the thermal behavior of the procured samples were characterized via X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), fourier transform infrared (FT-IR) spectroscopy, thermogravimetry-derivative thermal gravimetric (TG-DTG) and N2 adsorption–desorption isotherm. PLACKETT-BURMAN design was implemented as a screening method to examine the impacts of fifteen variables on physical properties of synthesized g -Al2O3 as a response variable. Specific surface area, pore volume and average pore diameter of the prepared samples were found to be within the ranges of 72-335.7 m2/g, 0.26-1.03 cm2/g and 4.6-15.2 nm, respectively. It was determined that the variables including pH value on the acidic region, time in the alkaline region and number of PH-SWING frequencies had major effects on the pore diameter of the procured g -Al2O3 powders. Calcination by steaming had the most significant effect on specific surface area, while the pH value on the acidic region had the greatest impact on pore volume.
