Graphdiyne, as a magical support, can anchor zero valence metal atoms, providing us with an opportunity to develop emerging catalysts with the maximized active sites and selectivity. Herein we report high‐performance atom catalysts (ACs), Cu 0 /GDY, by anchoring Cu atoms on graphdiyne (GDY) for hydrogen evolution reaction (HER). The activity and selectivity of this catalyst are obviously superior to that of commercial 20 wt.% Pt/C, and the turnover frequency of 30.52 s −1 is 18 times larger than 20 wt.% Pt/C. Density functional theory (DFT) calculations demonstrate that the strong p‐d coupling induced charge compensation leads to the zero valence state of the atomic‐scaled transition metal catalyst. Our results show the strong advantages of graphdiyne‐anchored metal atom catalysts in the field of electrochemical catalysis and opens up a new direction in the field of electrocatalysis.
