Abstract
Metal–organic frameworks (MOFs), notably Zeolitic Imidazolate Framework-67 (ZIF-67) and its derivatives, have garnered significant attention as versatile materials due to their distinct structural properties, including high surface area, open crystal structure, and tunable pore structures. ZIF-67 has been synthesized through various methods and intensification techniques, contributing to a vast amount of literature on their synthesis. This Review presents a thorough examination of synthesis methods, incorporating recent advancements, and explores the factors influencing the morphological and structural characteristics of ZIF-67. The paper outlines various intensification techniques for the synthesis of ZIF-67. Moreover, it addresses the challenges associated with the industrial-scale production of such materials and discusses the importance of reproducibility studies in ensuring consistency and reliability. Furthermore, the paper delves into the engineering aspects of ZIF-67 production and elaborates on the potential of ZIF-67 in the critical domain of hydrogen storage. This Review aims to offer comprehensive insight into the current state-of-the-art in ZIF-67 research, encouraging further exploration and innovation in this dynamic field.
