From: Substrate effect on hydrogen evolution reaction in two-dimensional Mo2C monolayers

The HER activity for the catalysts Pt (gray), Cu (green), Ag (red), and Au (dark yellow). The HER activity of the Mo2C on the corresponding substrates are shown. The vertical black line at − 0.18 eV represents the optimal value, and the activity of the catalysts are compared on the vertical line. A higher position on the line represents higher HER activity.
