Fig. 5. (a) The periodic table includes all MBenes with both experimental and theoretical investigations. Different colors represent the stable structural prototypes of these MBenes. (b) Calculation models depicting top and side views for various MBene structural prototypes have been constructed. (c) A schematic representation outlines the NRR mechanisms, highlighting the distal, alternating, and mixed pathways for different MBene structural prototypes. (d) The side view of the initial calculation models for M2B MBene structural prototypes is showcased, based on the proposed NRR intermediate species. Reproduced with permission from ref. 68.
