Performance of Platinum and Gold Catalysts Supported on Ceria-Zirconia Mixed Oxide in the Oxidation of Chlorobenzene

Popis výsledku v původním jazyce

Monometallic noble metal catalysts supported on ceria-zirconia mixed oxide were prepared by impregnation and tested in the oxidation of chlorobenzene (100 ppm in air). With the pure ceria-zirconia support, 27 % conversion was achieved at 400 °C and onlyincomplete oxidation to carbon monoxide was evidenced. The introduction of gold and especially platinum significantly improved the efficiency of the catalyst. The catalytic performance was increased with increasing noble metal content. The catalyst with1 wt. % of Pt achieved 97 % conversion of chlorobenzene already at 350 °C and complete oxidation to CO2 with only traces of by-products was detected. Platinum catalysts were more efficient than gold ones, which was ascribed to their superior redox properties. On the other hand, the lower acidity of platinum catalysts was not detrimental for their catalytic performance.
