Abstrakt: Context: The abilities of Co-Al 18 P 18 , Ni-Al 21 N 21 , Fe-B 24 N 24 , Mn-B 27 P 27 , Ti-C 60 and Cu-Si 72 as catalysts for N 2 -RR to create the NH 3 are investigated by theoretical levels. The ∆E adoption and ∆E formation of Co-Al 18 P 18 , Ni-Al 21 N 21 , Fe-B 24 N 24 , Mn-B 27 P 27 , Ti-C 60 and Cu-Si 72 are investigated. The ∆E adsorption of N 2 -RR intermediates and ΔG reaction of reaction steps of N 2 -RR on Co-Al 18 P 18 , Ni-Al 21 N 21 , Fe-B 24 N 24 , Mn-B 27 P 27 , Ti-C 60 and Cu-Si 72 are examined. In acceptable mechanisms, the *NN → *NNH step is potential limiting step and *NN → *NNH step in enzymatic mechanism is endothermic reaction. The ∆G reaction of *NHNH2 → *NH 2 NH 2 step on Co-Al 18 P 18 , Ni-Al 21 N 21 , Fe-B 24 N 24 , Mn-B 27 P 27 , Ti-C 60 and Cu-Si 72 are -0.904, -0.928, -0.860, -0.882, -0.817 and -0.838 eV, respectively. The Co-Al 18 P 18 and Ni-Al 21 N 21 have the highest ∆G reaction values for reaction steps of N 2 -RR. Finally, it can be concluded that the Co-Al 18 P 18 , Ni-Al 21 N 21 , Fe-B 24 N 24 and Mn-B 27 P 2 have acceptable potential for N 2 -RR by acceptable pathways.
Methods: The structures of Co-Al 18 P 18 , Ni-Al 21 N 21 , Fe-B 24 N 24 , Mn-B 27 P 27 , Ti-C 60 and Cu-Si 72 and N 2 -RR intermediates are optimized by PW91PW91/6-311+G (2d, 2p) and M06-2X/cc-pVQZ as theoretical levels in GAMESS software. The convergence for force set displacement of Co-Al 18 P 18 , Ni-Al 21 N 21 , Fe-B 24 N 24 , Mn-B 27 P 27 , Ti-C 60 and Cu-Si 72 and N 2 -RR intermediates are 1.5 × 10 5 Hartree/Bohr and 6.0 × 10 -5 Angstrom. The Opt = Tight and MaxStep = 30 are considered to optimize Co-Al 18 P 18 , Ni-Al 21 N 21 , Fe-B 24 N 24 , Mn-B 27 P 27 , Ti-C 60 and Cu-Si 72 and N 2 -RR intermediates. The frequencies of Co-Al 18 P 18 , Ni-Al 21 N 21 , Fe-B 24 N 24 , Mn-B 27 P 27 , Ti-C 60 and Cu-Si 72 and N 2 -RR intermediates are calculated.
