Selective oxidation of ethanol into acetaldehyde catalyzed by novel Mg-Mo/MCM-41 mesoporous molecular meshes

Molecular sieves of MCM-41 impregnated with MgO, MoO3, and Mo2C synthesized using a wet impregnation method. The compounds developed herein, were characterized by means of XRD, SEM-EDS and FT-IR techniques. The production capacity of acetaldehyde from ethanol was analyzed by catalytic processes empl...
