Description	This work compares catalytic properties of materials prepared by thermal pretreatment of hydrotalcite-like precursors and metal-supported materials. The attention is focused on two types of materials and two different reactions. Firstly, the activity of Ni-Al mixed oxides prepared by thermal pre-treatment of Ni-Al hydrotalcites is compared with that of supported Ni-based catalysts (Ni-alumina, Ni-alumina/meso) in the oxidative dehydrogenation of ethane and propane. The critical role in the activity and selectivity has been assigned to the population of NiO and its interaction with the support. Secondly, the attention is focused on basic catalysts and their activity in transesterification of rapeseed oil. The activity/stability of Mg-Al mixed oxides prepared by thermal pre-treatment of Mg-Al hydrotalcites is compared with that of supported potassium catalysts representing one of the most discussed solid catalysts for transesterification.
