“…Therefore, MBenes are expected to be applied as electrode and electrocatalysis materials. The applications for energy storage and electrocatalysis have been widely investigated theoretically by rst principles methods, including anodes of Li, Na, Mg ion batteries and Li-S batteries, as well as electrocatalysis for the hydrogen evolution reaction (HER), 8,30,36,39,58,59 oxygen evolution reaction (OER), 59 oxygen reduction reaction (ORR), 59 nitrogen reduction reaction (NRR), [31][32][33]35,54,[60][61][62][63] carbon dioxide reduction reaction (CO 2 RR), 64,65 nitric oxide reduction reaction (NORR), 34,66 and urea production. 67…”
