Figure 3. Melt-quenching simulation of ZIF-4 at zero pressure using deep learning force field. (A) Atomic configurations of ZIF-4 at different stages of the melt-quenching process, i.e., ZIF-4 crystal, molten ZIF-4 at 1,500 K, and quenched ZIF-4 glass at 300 K; (B-D) Calculated (B) pair distribution functions, (C) N-Zn-N bond angle distribution functions, and (D) pore size distribution of the ZIF-4 crystal, melt (at 1,500 K), and glass.
