Metal carbides M 2 C (MXenes) with two‐dimensional (2D) structure have been indicated as promising materials for N 2 fixation, with the activity being related to edge planes. Here, it is instead demonstrated that the transformation from a 2D‐ (nanosheets) to a 3D‐type nanostructure (nanoribbons) leads to a significant enhancement of the N 2 fixation activity due to the formation of exposed Ti−OH sites. A linear relationship is observed between ammonia formation rate and amount of oxygen on the surface of Ti 3 C 2 MXene.
