The preparation of chemically modified graphene (CMG) generally involves the reduction of graphite oxide (GO) by using various reducing reagents. Herein, we report a free‐radical‐promoted synthesis of CMG, which does not require any conventional reductant. We demonstrated that the phenyl free radical can efficiently promote the conversion of GO into CMG under mild conditions and produces phenyl‐functionalized CMG. This pseudo‐“reduction” process is attributed to a free‐radical‐mediated elimination of the surface‐attached oxygen‐containing functionalities. This work illustrates a new strategy for preparing CMG that is alternative to the conventional means of chemical reduction. Furthermore, the phenyl‐functionalized graphene shows an excellent performance as an electrode material for lithium‐battery applications.
