Fig. 3From: First-principles investigation of adsorption behaviors of small molecules on penta-grapheneTotal electronic density of states (DOS) for molecule-PG systems (black), and projected DOS for small molecules (blue line with green shadow) and PG (red) in the adsorption system: a CO, b H2O, c H2S, d NH3, e SO2, and f NO. The Fermi level is set to zero (see the dash line)Back to article page
