Patent

CA 2608757

A method for producing a high surface area iron material starting with a low surface area iron metal is disclosed. The iron material of the present invention has a surface area of at least about 200 m2/g, and is prepared via a method which comprises reacting a low surface area iron metal with oxygen and an organic acid. The high surface area iron material formed via this method is essentially free of contaminants.

La présente invention se rapporte à un procédé permettant de produire un matériau ferreux à surface active élevée à partir d'un métal ferreux à surface active réduite. Le matériau ferreux selon l'invention présente une surface active supérieure ou égale à 200 m2/g, et est obtenu à l'aide d'un procédé qui consiste à faire réagir un métal ferreux à surface active réduite avec de l'oxygène et un acide organique. Le matériau ferreux à surface active élevée formé à l'aide dudit procédé est sensiblement exempt de contaminants.
