[ 1 ] - Surface modification of γ-alumina by NaNO2, NaNO3, HNO2, HNO3 and H2SO4: A DFT-D approach
In this study, the dissociative adsorption of NaNO2, NaNO3, HNO2, HNO3 and H2SO4 over (1 1 0) surface of γ-alumina non-spinel model were investigated through the dispersion corrected density functional theory (DFT-D) at PBE-D/DNP level of calculation. It was found that all of the species are dissociated to their ionic forms after...

[ 3 ] - Effect of NaNO2, HNO3 and H2SO4 on the structure and reactivity of gamma-alumina
The influence of NaNO2, HNO3 and H2SO4 on the structure and morphology of gamma-alumina was investigated by XRD, BET, SEM and FT-IR spectroscopy. Selected amounts of NaNO2, HNO3 and H2SO4 were added to a solution of aluminum isopropoxide (as a precursor for the boehmite synthesis). The boehmite samples were calcined at 350 and 600 ℃ to form the semi-crystalline high surface area gamma-Al2O3. Th...
