Figure 1. (A) Representative geometric structure of the M7S12 ic-2Ds (σ = 33%) from the top and the side views. M atoms are denoted in blue, and S atoms are denoted in orange for the first layer and yellow for the second layer in each MS2 layer for better visual distinction, respectively. (B) Procedure to screen potential ic-2D electrode materials and HER electrocatalysts.
