Partially oxidized carbonaceous materials characterized by substantially homogenous, partially oxygenated surfaces thereof are enabled via microwave-assisted methods that are simple and fast. The exemplary methods include combining carbonaceous material(s), at least one mild oxidizer, at least one nucleophile, and an aqueous solvent system to obtain a mixture; and exposing the mixture to microwave radiation for a predetermined time to produce partially oxidized carbonaceous materials. The predetermined time may be in a range from about 5 seconds to about 2 hours, and the power of the microwave energy may be in a range from about 100 w to about 1700 W. The partially oxidized carbonaceous materials are characterized by a homogeneous distribution of oxygen content in surfaces thereof, in nonzero amounts up to about 10 at %, and a standard deviation of surface oxygen content in a range from about 0.1 at % to about 1.0 at %.
