Abstract
A wash-coat () for use as a support for an active catalyst species () and a catalytic combustor component () incorporating such wash-coat. The wash-coat is a solid solution of alumina or alumina-based material (AlO-0-3 wt % LaO) and a further oxide exhibiting a coefficient of thermal expansion that is lower than that exhibited by alumina. The further oxide may be silicon dioxide (2-30 wt % SiO), zirconia silicate (2-30 wt % ZrSiO), neodymium oxide (0-4 wt %), titania (AlO-3-40% TiO) or alumina-based magnesium aluminate spinel (AlO-25 wt % MgO) in various embodiments. The active catalyst species may be palladium and a second metal in a concentration of 10-50% of the concentration of the palladium.
