Both multilayered (ML) and few-layered (FL) Ti 3 C 2 T x nanosheets have been prepared through a typical etching and delaminating procedure. Various characterizations confirm that the dominant terminal groups on ML-Ti 3 C 2 T x and FL-Ti 3 C 2 T x are different, which have been assigned to O-related and hydroxyl groups, respectively. Such deviation of the dominant terminals results in the different physical and chemical performance and eventually makes the nanosheets have different potential applications. In particular, before coupling to Ag nanoparticles, ML-Ti 3 C 2 T x can present stronger near-field enhancement effect; however, Ag/FL-Ti 3 C 2 T x hybrid structure can confine stronger near-field due to the electron injection, which can be offered by the terminated hydroxyl groups.
