A method for delignifying wood pulp is disclosed. The method comprises the steps of obtaining a wood pulp and exposing the wood pulp to a polyoxometalate of the formula: (VnMomW1NboTap(TM)q(MG)rOs)x- where n is 1-18, m is 0-40, l is 0-40, o is 0-10, p is 0-10, q <= 6, r <= 6, TM is a d-electron-containing transition metal ion, and MG is a main group ion, provided that n + m + o + 1 + p >= 4 and s is sufficiently large that x > o. The exposure is under conditions wherein the polyoxometalate is reduced. In a preferable form of the invention, the method additionally comprises the step of reoxidizing the polyoxometalate. |
