The review covers the recent developments in the field of novel micro-mesoporous materials obtained by zeolite recrystallization. The materials are classified into three distinctly different groups depending on the degree of recrystallization: (i) coated mesoporous zeolites (RZEO-1); (ii) micro-mesoporous nanocomposites (RZEO-2); and (iii) mesoporous materials with zeolitic fragments in the walls (RZEO-3). The first part of the review is focused on the analysis of the synthetic strategies leading to different types of recrystallized materials. In the second part, a comprehensive view on their structure, texture and porosity in connection with acidic and diffusion properties is given. The last part is devoted to the catalytic applications of recrystallized materials. The advantages and disadvantages with respect to pure micro- and mesoporous molecular sieves and other hierarchical zeolites are critically analyzed and the future opportunities and perspectives are discussed.
该综述涵盖了沸石重结晶得到的新型微孔-介孔材料领域的最新进展。根据重结晶程度，这些材料可分为三类截然不同的组：（i）包覆介孔沸石（RZEO-1）；（ii）微-介孔纳米复合材料（RZEO-2）；和（iii）沸石碎片存在于孔壁中的介孔材料（RZEO-3）。综述的第一部分侧重于分析导致不同类型重结晶材料的合成策略。在第二部分中，给出了它们的结构、织构和孔隙率与酸性和扩散性能的综合观点。最后一部分致力于重结晶材料的催化应用。对其相对于纯微孔和介孔分子筛以及其他分级沸石的优缺点进行了批判性分析，并讨论了未来的机遇和前景。
