Abstract
In this work, a synthesis method of coating with thin layers of MgAl2O4 or ZnAl2O4 over α-Al2O3 spheres were developed. The method consisted in the deposition of a primer of bohemite on the spheres, followed by the impregnation with a solution of Mg or Zn nitrates, and further thermal treatments in order to obtain MAl2O4 (M: Mg or Zn). This method was modified to improve the thickness and purity of the layer material. With this method, layers of uniform and adequate thickness and good adhesion were achieved. Pt catalysts prepared with these materials as supports displayed good catalytic performances in the n-butane dehydrogenation reaction, especially those obtained with purified supports.
