Abstract
Experimental data on hydrogen production via a partial oxidation of methanol (POM) reaction on Au/ZrO2, Au/CeO2-ZrO2 and Au/CeO2-ZrO2-TiO2 catalysts is presented in this article. The gold catalysts were prepared by a deposition-precipitation (DP) method and characterized by XRF, XRD, H-2-TPR, XPS methods N-2 adsorption. The activity results show that the catalyst containing 1 wt% gold supported on a CeO2-ZrO2 carrier demonstrates very good hydrogen selectivity and the highest catalytic activity among all tested catalysts. The optimal working temperature established was 375 degrees C. At this temperature 75.5% hydrogen selectivity was registered. The presence of oxidized gold in the catalyst's composition as well as the support redox properties are the major factors controlling the observed catalytic activity.
