The metal-free oxidation of organic compounds is one of the most demanding reactions in chemical industries. As such, iodoxybenzoic acid (IBX) is an attractive reagent due to its metal-free oxidative activity. To apply IBX for the alcohol oxidation in water, IBX was immobilized on graphene oxide (GO). GO-supported IBX reagent exhibited excellent performance for alcohol oxidation reaction in water with greater than 90% selectivity. It could be reused without significant loss of oxidative activity.
