摘要: A method is provided for delignifying and bleaching a lignocellulose material, wherein an aqueous solution of a redox catalyst and an oxidant is reacted with the material. The catalyst comprises an organometallic cation of the general formula [(1) Mno 2 Mn (L)] n+, wherein Mn is manganese (III) or (IV) oxide, the two Mn's of this cation may form a pair in a III-III, III-IV or IV-IV oxidative state, n is 2, 3 or 4, O is oxygen, and L is a ligand comprising 4 nitrogen atoms co-ordinating the manganese.
