Název v původním jazyce

Effect of potassium in calcined Co-Mn-Al layered double hydroxide on the catalytic decomposition of N2O

Popis výsledku v původním jazyce

A series of catalysts was prepared by thermal treatment of the coprecipitated Co-Mn-Al layered double hydroxide doped with various amount of potassium. The samples were tested for N2O decomposition to determine the effect of K addition on the catalytic activity in the presence of O2, NOx and H2O. An optimum K content of ca. 0.9-1.6 wt% was found to achieve a high catalytic activity in the presence of O2 and H2O, while the non-modified Co-Mn-Al mixed oxide was the most active catalyst in the presence ofO2 and NOx. The addition of potassium to the Co-Mn-Al mixed oxide apparently results in a modification of both electronic properties of active metals and acid-base function of the catalyst surface.
