DEVELOPMENT AND USE OF IRON BASED CATALYST FOR IMPLEMENTING OXIDATION-REDUCTION METHOD FOR SUBSTANCES TO BE REDUCED

摘要

The invention relates to the use of a ferrous ferric oxyhydroxy salt of the dual lamellar hydroxide family as a catalyst, or as a precursor of said catalyst having the same crystalline structure as said catalyst, for implementing an oxidation-reduction method, said ferrous ferric oxyhydroxy salt being used in association with ferri-reducing bacteria capable of reducing Fe ^III into Fe^II in the presence of organic material, in order to reduce a substance (S) into a reduced substance, the redox potential of the ^Sreduced /^S couple being higher than that of the Fe ^II/Fe^III couple at the crystallographic sites of Fe^II.
