Disclosed is a catalyst carrier having excellent durability, which has high catalytic ability without increasing the specific surface area thereof. Also disclosed is a catalyst using the catalyst carrier. Specifically disclosed is a catalyst carrier composed of a metal oxycarbonitride. The metal oxycarbonitride preferably contains at least one metal selected from the group consisting of niobium, tin, indium, platinum, tantalum, zirconium, copper, iron, tungsten, chromium, molybdenum, hafnium, titanium, vanadium, cobalt, manganese, cerium, mercury, plutonium, gold, silver, iridium, palladium, yttrium, ruthenium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and nickel. Also specifically disclosed is a catalyst which is composed of the catalyst carrier and a catalyst metal supported by the catalyst carrier.

L'invention porte sur un support de catalyseur ayant une excellente durabilité, qui a une capacité catalytique élevée sans augmenter la surface spécifique de celui-ci. L'invention porte également sur un catalyseur utilisant le support de catalyseur. De façon spécifique, l'invention porte sur un support de catalyseur composé d'un oxycarbonitrure métallique. L'oxycarbonitrure métallique contient de préférence au moins un métal choisi dans le groupe constitué par le niobium, l'étain, l'indium, le platine, le tantale, le zirconium, le cuivre, le fer, le tungstène, le chrome, le molybdène, le hafnium, le titane, le vanadium, le cobalt, le manganèse, le cérium, le mercure, le plutonium, l'or, l'argent, l'iridium, le palladium, l'yttrium, le ruthénium, le lanthane, le cérium, le praséodyme, le néodyme, le prométhium, le samarium, l'europium, le gadolinium, le terbium, le dysprosium, l'holmium, l'erbium, le thulium, l'ytterbium, le lutétium et le nickel. De façon spécifique, l'invention porte également sur un catalyseur qui est composé du support de catalyseur et d'un métal catalyseur supporté par le support de catalyseur.
