Many research groups are focused on the development of suitable catalysts for this reaction because it is still a problem to find the catalyst with sufficient activity and stability in real off-gas conditions due to water, oxygen and NOx inhibition effects. Multicomponent mixed oxides prepared by thermal treatment of layered double hydroxide (LDH) precursors seem to be promising catalysts for this reaction. Layered double hydroxides with general chemical composition of [MII1-xMIIIx(OH)2]x+[An-x/n.yH2O]x- where MII and MIII are divalent and trivalent metal cations and An- is an n-valent anion (often carbonate) consist of positively charged hydroxide layers separated by interlayers containing anions and water molecules. Thermal treatment of LDH precursors gives finely dispersed mixed oxides of MII and MIII with large surface area and good thermal stability. Presented contribution will present intrinsic kinetic data obtained in laboratory experiments of N2O decomposition over grained LDH-related mixed oxides as well as results of pilot plant experiments in real off gas from nitric acid production.
