Catalytic system rhodium oxide modified for N2O decomposition in o2 n2 and cerium.

摘要

Rhodium catalyst systems and modified for the decomposition of N {2} O N_ {2} in ceria and O_ {2}.; The present invention discloses a catalyst system comprising an active phase of rhodium supported on a mixed oxide of cerium and one or more metals selected from the groups of transition metals and internal transition for example Pr, La, Zr, Y, Th or Sm and a support such as alumina. The invention also describes a process for obtaining the catalytic system, and the use thereof for removal and / or reduction of the content N_ {2} or a gas comprising the same, for example an effluent from anthropogenic sources as or a diesel engine industry.
