Abstract
Mechanochemical synthesis has been successfully employed to prepare Cu0–Al2O3 composite powders. The formation of the designed compound is due to the self-propagating reaction of CuO and Al0 powders by high-energy ball milling using a planetary ball mill (Pulverissette 6, Fritsch GmbH). The products were characterized by means of nitrogen adsorption (BET surface area), X-ray diffraction, scanning electron microscopy and temperature-programmed reduction of hydrogen. The catalytic properties of the prepared materials were tested in the methanol steam reforming (SRM) process. The results show that the Cu0–Al2O3 system is active towards hydrogen in SRM. Hydrogen yields are satisfactory; however, methanol conversion to CO as a by-product is observed.
