According to Du et al. [18], during the initial stage, a high Na⁺ ion concentration in the system contributes to forming smaller zeolite particles by limiting the polymerization extent. Primary nanosized zeolite crystals are therefore formed at that stage (a–c). At the same time, due to the instability in the hydrothermal synthesis system, the dissociative nanocrystals attract each other and form loose aggregates by self-assembly (c,d). The inner nanocrystals are difficult to grow because of the confined spaces, while the nanocrystals outer can further grow epitaxially and form the oriented “petals” (d,e).
