Title (EN) NICKEL-COBALT-BASED CATALYSTS FOR CO AND NO OXIDATION; THEIR ACTIVATION
(FR) CATALYSEURS À BASE DE NICKEL-COBALT POUR OXYDATION DE CO ET DE NO; LEUR ACTIVATION
Abstract:
(EN) A catalyst obtainable by exsolving particles of Ni, Co and/or a mixture of Ni and Co from a perovskite metal oxide of formula (I) (M1aM2b)(CoxNiyM3z)O3, wherein M1 and M2 are each independently an alkali earth metal or a rare earth metal, M3 is Ti or Cr, 0 ≤ a ≤ 1, 0 ≤ b ≤ 1, 0 < a + b ≤1, 0 ≤ x < 1, 0 ≤ y < 1, 0 ≤ z < 1, x + y + z = 1 and where at least one of x and y > 0. The invention includes methods of converting this catalyst into one or more catalytically active forms. The catalysts and the activated forms of same are useful in the catalysing CO oxidation and/or NO oxidation.
(FR) Un catalyseur pouvant être obtenu par exsolution de particules de Ni, de Co ou d'un mélange de Ni et de Co à partir d'un oxyde métallique de pérovskite de formule (I) (M1 aM2 b)(CoxNiyM3 z)O3, où M1 et M2 sont chacun de façon indépendante un métal alcalino-terreux ou un métal des terres rares, M3 représente Ti ou Cr, 0 ≤ a ≤ 1, 0 ≤ b ≤ 1, 0 < a + b ≤1, 0 ≤ x < 1, 0 ≤ y < 1, 0 ≤ z < 1, x + y + z = 1 et où au moins l'un de x et y > 0. L'invention comprend des procédés de conversion de ce catalyseur en une ou plusieurs formes catalytiquement actives. Les catalyseurs et leurs formes activées sont utiles dans l'oxydation catalytique de CO ou l'oxydation de NO.
