摘要： A composition for catalysis of a Haber-Bosch process comprises an anion vacant lattice and a Haber-Bosch catalyst (e.g. Fe Ru). Suitable anion vacant lattices include oxynitrides and oxides, which may be doped or undoped, including CeaMbO2-XNY (Formula III) M is one or more elements with a valence lower than +4. “a” and “b” are independently in the range 0.05 to 0.95, with the proviso that “a” and “b” together sum to 1 (approximately). X is greater than 0 and less than 2. Y is greater than zero and less than or equal to X. A process employing the composition produces ammonia.

摘要： A composition for catalysis of a Haber-Bosch process to produce ammonia; a process employing the composition and an anion vacant lattice for use in the process.
The composition comprises an anion vacant lattice and a Haber-Bosch catalyst (e.g. Fe or Ru). Suitable anion vacant lattices include oxynitrides and oxides, which may be doped or undoped, including


CeaMbO2-xNy  (Formula III)

M is one or more elements with a valence lower than 4. “a” and “b” are independently in the range 0.05 to 0.95, with the proviso that “a” and “b” together sum to 1 (approximately). X is greater than 0 and less than 2. Y is greater than zero and less than or equal to X.

摘要： A solid ionic conducting material for use in an electrochemical device comprises an oxyhydroxide or hydrated oxide derived from of an oxide with a perovskite, Brownmillerite, layered oxide, and/or K4CdCl6 structure, the elemental composition of the initial oxide being selected to provide suitable conduction properties for the derived anhydrous or hydrated oxyhydroxide or hydrated oxide. A method of making such a solid ionic conducting material, including treatment with water, and an electrochemical device incorporating such a solid ionic conducting material (optionally as an electrolyte) are also disclosed.
