Ni nanoparticles supported on microwave-synthesised saponite for the hydrogenation of styrene oxide
Abstract 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.
Research Highlights ► Saponites were synthesised with microwaves at different preparation conditions. ► Saponite impregnated Ni catalysts were active and very selective to 2-phenylethanol. ► Saponite impregnated Ni catalysts were very resistant to deactivation. ► Higher Ni content or saponites synthesised at lower pH improved catalytic results. ► Catalytic results were related to different NiO-saponite interactions.
