A method for catalytic oxidation of cellulose using a heterocyclic nitroxyl radical as catalyst and main oxidant acting as oxygen source comprises, before the catalytic oxidation of the cellulose, pretreatment of the cellulose
- in an alkaline pretreatment step, where the cellulose is treated in alkaline solution having hydroxide concentration of above 0.3 M, and
- in a washing step, where the cellulose treated in the alkaline solution is washed to lower the pH.
