Several saponites were synthesised under microwaves, at different preparation conditions, to be used as supports of nickel nanoparticles for the catalytic hydrogenation of styrene oxide to 2-phenylethanol. Ni/saponites obtained by impregnation with the highest nickel content (20 wt.%) or by using saponites synthesised at lower pH (pH = 7) resulted in high activity, high selectivity to 2-phenylethanol, and high resistance to deactivation catalysts. Catalytic results were related to the different NiO-saponite interactions observed by TPR.
