The effect of calcination temperature (450-800~ and copper loading (lower and higher than 4wt%) on the catalytic behaviour and structure of Cu/Ni/K//y-A1203 catalysts were analysed. These catalysts were proven to be suitable for the steam reforming of ethanol. XPS, SEM-EDX, XRD and N20 chemisorption techniques were employed; catalytic activity is evaluated using the steam reforming of ethanol as the test reaction. Depending of both, copper loading and calcination temperature, a non-stoichiometric surface spinel can be obtained which has catalytic properties. The presence of a layered double hydroxide precursor is essential for the formation of this phase
