合成用于广泛应用的沸石的核心目标是生产具有超过常规对应物的性质和相应性能的材料。这推动了对结晶过程的阐明和控制，其中最关键的设计标准之一是制备具有超小尺寸的沸石晶体以减轻质量传输限制的有害影响的能力。在最基本的层面上，这需要全面了解成核，以解决这一普遍存在的材料差距。这一观点强调了最近的方法来改变沸石成核，通过使用种子辅助协议和利用沸石间的转换来设计先进的材料。在用于合成沸石的复杂生长介质中引入晶种可对最终产物的物理化学性质具有广泛的影响。在这里，我们讨论了沸石成核的不同途径，最近在种子辅助合成的纳米级和分层材料的突破，和缺点，发展广义的指导方针，以预测合成结果。我们提供了一个国家的最先进的方法来定制沸石结晶的批判性分析，其中我们概念化网络理论和沸石合成之间的相似之处是否可以用于翻译的关键发现的个人发现在更广泛的沸石晶体结构和/或合成条件。
A core objective of synthesizing zeolites for widespread applications is to produce materials with properties and corresponding performances that exceed conventional counterparts. This places an impetus on elucidating and controlling processes of crystallization where one of the most critical design criteria is the ability to prepare zeolite crystals with ultrasmall dimensions to mitigate the deleterious effects of mass transport limitations. At the most fundamental level, this requires a comprehensive understanding of nucleation to address this ubiquitous materials gap. This Perspective highlights recent methodologies to alter zeolite nucleation by using seed-assisted protocols and the exploitation of interzeolite transformations to design advanced materials. Introduction of crystalline seeds in complex growth media used to synthesize zeolites can have wide-ranging effects on the physicochemical properties of the final product. Here we discuss the diverse pathways of zeolite nucleation, recent breakthroughs in seed-assisted syntheses of nanosized and hierarchical materials, and shortcomings for developing generalized guidelines to predict synthesis outcomes. We offer a critical analysis of state-of-the-art approaches to tailor zeolite crystallization wherein we conceptualize whether parallels between network theory and zeolite synthesis can be instrumental for translating key findings of individual discoveries across a broader set of zeolite crystal structures and/or synthesis conditions.
