| Abstract: | Catalytic activity of hydrogen storage alloy, Mg2Ni and modified Mg2Ni(O-Mg2Ni) has been studied using decomposition of 2-propanol as test reaction. Besides dehydrogenation activity, Mg2Ni shows some activity towards the formation of condensation products, viz. mesityl oxide, isobutyl methyl ketone and diisobutyl ketone. XRD of spent Mg2Ni indicate disproportionation of Mg2Ni to MgO, Ni and NiO under reaction conditions, while XP spectra show coke formation on its surface. On O-Mg2Ni the activity is reproducible with only acetone as the product. The activity, selectivity and stability have been explained based on the difference in their surface composition as revealed by XPS studies. |
