Atmospheric plasma treated hydrotalcite-type catalyst

Popis výsledku v původním jazyce

This work is devoted to studying the influence of plasma treatment on catalytic properties of hydrotalcite-type catalysts. Hydrotalcite-type catalysts with Mg/Al molar ratio 3:1 were prepared by co-precipitation from mixed solution of magnesium nitrate and aluminium nitrate using mixed solution of potassium carbonate and potassium hydroxide. Nonthermal atmospheric pressure dielectric barrier discharge (DBD) under defined conditions was used for modification of these catalysts. Catalysts were studied either without treatment or after calcination or with subsequent plasma modification for both cases. Catalysts were characterized by XPS, SEM, XRD, XRF and BET techniques. Catalytic activity was tested using aldol condensation of furfural and acetone. The investigated catalysts showed different catalytic performance - the plasma treatment increased the conversion of the furfural and also the selectivity of the reaction to create the desired products. Only 4s plasma treatment lead to better results than calcination at 450°C/6h. The best catalytic activity was achieved in case of calcined plasma treated hydrotalcite.
