Chemical Coordination Induced Fullerene Dimers on Hot Pt(111)
Abstract
Abstract The fullerene family is known for its unique properties, facilitating the formation of large, lubricated nano‐onions and the fragmentation into small carbon clusters through various processes. In this study, we explore the thermal evolution of islands on Pt(111), focusing on the segregation of islands, the formation of fullerene dimers, and the subsequent development of large graphene sheets. Using noncontact atomic force microscopy and scanning tunneling microscopy, we observed that after annealing at , the islands showed minimal change compared to their deposition at room temperature. However, at , pairs of separated dimers appeared, which, due to their low mobility, have the potential to transform into graphene quantum dots (GQDs). Further annealing at controlled and refined the quality and dimensions of the graphene patches. This process not only provides an effective method for producing high‐quality graphene but also permits to preserve isolated dimers on the Pt(111) surface, offering valuable insights for advanced synthesis and lubrication applications.
