Abstract

Hexagonal mesoporous aluminophosphate (HMA) materials were synthesized using cetyltrimethylammonium bromide as a structure directing agent and industrial aluminum dross powder or Al(OH)3 extracted from Al dross as an aluminum source at room temperature. XRD confirmed the presence of ordered mesostructures in all of the prepared HMA samples, and textural properties of the prepared samples were close to those of HMA prepared using_x000D_ pure chemicals. Uniform pore structure of the materials prepared using the industrial Al dross was confirmed by TEM, and N2 adsorption-desorption isotherms of the HMA samples showed type IV isotherms with surface area in the range of 410-560 m2/g. Cr-containing HMA (CrHMA) samples were also prepared using industrial aluminum dross as an aluminum source, which demonstrated virtually identical catalytic performances in liquid phase tetralin oxidation reaction_x000D_ to those obtained over a CrHMA catalyst prepared using pure chemicals.
