Název v původním jazyce

Optimization of CeO2-ZrO2 mixed oxide catalysts for ethyl acetate combustion

Popis výsledku v původním jazyce

Nanosized ceria-zirconia mixed oxides were prepared using template-assisted co-precipitation approach followed by a hydrothermal treatment step. Some synthesis parameters (Ce/Zr ratio, presence of template and hydrothermal treatment temperature) were varied in order to get highly active mixed oxide catalysts for ethyl acetate combustion. The performed physicochemical characterization evidenced the presence of a single cubic phase for the samples with lower Ce content (Ce/Zr<5:5 mol ratio). Surprisingly,formation of separate tetragonal zirconia phase along with the cubic one was registered for the mixed oxide samples with lower Zr amount (Ce/Zr=5:5 mol ratio). The variation of the other two synthesis parameters had an effect mostly on the textural characteristics of the final materials. The most significant effect on the catalytic properties of mixed Ce-Zr oxide samples comes from varying Ce-Zr ratio. Highest catalytic activity showed 3Ce7Zr(CTAB, HT373) sample due to the complete inte
