Scientific Achievement
Density functional theory (DFT) calculations demonstrate that Aluminum-doped graphene is a versatile non-transition metal catalyst for the reduction of nitrogen into ammonia.
Significance and Impact
From the DFT-based study, a detailed understanding of a heteroatom-assisted H transfer mechanism provides a design rule for future synthetic catalysts targeting nitrogen fixation based on earth-abundant materials.
