Abstract

In one aspect, TEMPO-cellulose structures and method of making the same are described herein. Briefly, a method of synthesizing TEMPO-cellulose comprises disposing cellulose in an aqueous medium, disposing first and second oxidizing agents in the aqueous medium and oxidizing hydroxyl groups of the cellulose via the first and second oxidizing agents in the presence of a 2,2,6,6-tetramethylpiperidine 1-oxyl radical (TEMPO) catalyst.
