In situ doping and synthesis of two-dimensional nanomaterials using mechano-chemistry
Doping foreign atoms into materials can modify their electronic configuration and tune their chemical and physical properties. Developing an efficient doping strategy is thus critically important for many new applications of two-dimensional (2D) nanomaterials. Here, we report an in situ process to produce and simultaneously dope carbon and nitrogen in a number of 2D materials including graphene, BN, MoS2 and WS2 using mechanochemistry. This new process produces large quantities of 2D materials with controlled doping contents and new properties.
