As shown in Fig. 2d, the large crystal particles with smooth surface can be observed from the SEM image of initial MOFs. WebMOF gel formation consists of two separate steps: the nucleation of a large amount of discrete MOF nanoparticles, and subsequent gelation to form a colloidal network structure. Both aspects require careful regulation, especially the latter which usually competes against more thermodynamically favourable processes of precipitation.
