Ternary metal oxide solid solutions containing permutations of magnesium, nickel, and cobalt with trivalent metals such as aluminum, chromium, gallium, and iron show unusual resistance to rehydration. A composite comprising a) a ternary metal oxide solid solution of formula, Aa(II)Bb(II)Cc(III)O(a+b
Ternary metal oxide solid solutions containing permutations of magnesium, nickel, and cobalt with trivalent metals such as aluminum, chromium, gallium, and iron show unusual resistance to rehydration. A composite comprising a) a ternary metal oxide solid solution of formula, Aa(II)Bb(II)Cc(III)O(a+b+c)(OH)c where: a, b, and c are atom fractions of A(II), B(II), and C(III), respectively; C(III) is a trivalent metal cation whose metal is selected from the group consisting of Al, Cr, Ga, Fe, and combinations thereof, and combinations of Al and metals of atomic number 57 through 71; A(II) and B(II) are divalent metal cations and i. A is Mg, B is Ni, and 0.05≤a/(a+b)≤0.5; or ii. A is Mg, B is Co, and 0.05≤a/(a+b)≤0.75; or iii. A is Co, B is Ni, and 0.05≤a/(a+b)≤0.95; and 1.5≤(a+b)/c≤5.0; and b) at least one catalytically active species selected from the group consisting of zeolites, synthetic molecular sieves; clays and pillared clays; and molybdenum, vanadium, copper, chromium, manganese, silver, and titanium in an upper valence state, are hydrothermally stable catalysts.
