The production of hydrogen directly from dimethyl ether (DME) was performed on bifunctional Cu-Ce/Al2O3 catalysts. The catalysts were characterized by XRD, HRTEM, EDX and IR spectroscopy of low-temperature CO adsorption.
The high hydrogen productivity up to 600 mmol g-1h-1 may be explained by assuming that (1) DME dehydration occurs on acid sites of Ȗ-Al2O3 and (2) methanol steam reforming takes place on mixed oxide phase CuO-CeO2, solid solution of
copper ions in cerium dioxide with ratio Cu/Ce from 12/86 to 33/67 at.%.
