Fig. 5: Projected density of states (PDOS) of ground states of nine adsorbed structures on catalysts.
From: Photo-thermo semi-hydrogenation of acetylene on Pd1/TiO2 single-atom catalyst

a Pd/TiO2-a101-1. b Pd/TiO2-a101-2. c Pd/TiO2-r110. Density of states that projected onto different kinds of atoms are drawn with different color: C: pink, H: red, Pd: blue, Total DOS: black. Fermi level has been shifted to 0 eV and marked by orange dashed line.
