Exposure of the ZIF-8 crystal to the electron beam causes fading intensity and displacement of Bragg planes, indicating a loss of structural integrity. The fading of the intensity of the Bragg plane indicates defect formation and bond breaking in the crystal, whereas the displacement in the Bragg plane signifies volume shrinkage. The results of fig. (a) indicates that the high index planes (such as {400} and {431}) fade faster as compared to low index planes (such as {110}, {211}, {200} and {222}). Fig. also shows the relative displacement of different Bragg planes, indicating that high-index planes collapse first as compared to low-index planes at 300 kV.
