Abstract: With the ongoing effort in proposing and realizing functional two-dimensional (2D) materials, we predict by first-principles calculations a family of 2D metal-carbon (M–C) crystals consisting of M–C trigonal lattice interpenetrated with the metal buckled honeycomb structure. We suggest by simulations that the 2D M–C crystals can be readily fabricated by a self-organizing lattice reconstruction process after placing metal atoms on hollow sites of ?-graphyne. In total, we found 12 members of the family and they exhibit a variety of electronic and magnetic properties. In this work, we highlight and focus on the Fe member of the family, 2D-Fe2C12. Each Fe in 2D-Fe2C12 has a magnetic moment of 1 ?B due to the spin splitting of Fe E1 bands at Fermi surface, resulting in half metallicity and high catalytic activity with unusually high-density single-atom Fe active sites. Ab initio molecular dynamics simulations revealed that the 2D-Fe2C12 retains its structural integrity up to 700 K of simulated short duration annealing. We expect these results to stimulate experimental research for the 2D M–C crystals we proposed. © 2021, The Author(s).
