A process for the preparation of reticulated copper sulfide and/or nickel sulfide which process comprises the steps of: (i) subjecting a mixture comprising copper sulfide and/or nickel sulfide powder and a salt to sintering by hot isostatic pressing at elevated temperature and elevated pressure, the said salt being physically and chemically stable under the hot isostatic pressing conditions; and (ii) dissolving the salt from the sintered body by treating the sintered body with a solvent in which the said salt is soluble. The use of reticulated copper sulfide and/or nickel sulfide prepared according to the method above as an electrocatalytic material.
L'invention concerne un procédé de préparation de sulfure de cuivre et/ou de nickel réticulé qui consiste en ce qui suit: (i) soumettre au frittage par compression isostatique à chaud un mélange comprenant une poudre de sulfure de cuivre et/ou de nickel ainsi qu'un sel, à une température et une pression élevées, ledit sel étant physiquement et chimiquement stable à une température et à une pression élevées, et; -ii) laver le sel du corps fritté en traitant ledit corps fritté avec un solvant qui dissout ce sel. L'invention se rapporte aussi à l'utilisation en tant que matériau électro-catalytique d'un sulfure de cuivre et/ou de nickel réticulé préparé selon le procédé ci-décrit.
