Metal organic frameworks (MOFs) have been investigated extensively for separation, storage, catalysis, and sensing applications. Nonetheless, problems associated with their toxicity, recycling/reuse/regeneration, and degradation have yet to be addressed as one criterion to satisfy their commercialization. Here, the challenges associated with MOF-based technology have been explored to further expand their practical utility in various applications. We start a brief description of challenges associated with MOF-based technology followed by a critical evaluation of toxicity and need of technical options for regeneration of MOFs. Importantly, diverse techniques/process for reuse and regeneration of MOFs like activation of MOFs by heat, vacuum, solvent exchange, supercritical carbon dioxide (SCCO) and other miscellaneous options have been discussed with recent examples. Afterward, we also present an economical aspect and future perspectives of MOFs for real world applications. All in all, we aimed to present opportunities and critical review of the current status of MOF technology with respect to their recycling/reuse/regeneration to consider their environmental impact.
金属有机骨架（MOFs）已广泛应用于分离、储存、催化和传感等领域。然而，其毒性、回收/再利用/再生和降解等问题仍未得到解决，这是满足其商业化的一个标准。在这里，我们探讨了与 MOF 相关的技术挑战，以进一步扩大其在各种应用中的实际效用。我们首先简要描述了与 MOF 相关的技术挑战，然后对毒性和 MOF 再生的技术选择进行了批判性评估。重要的是，我们讨论了各种用于 MOF 再利用和再生的技术/工艺，如通过热、真空、溶剂交换、超临界二氧化碳（SCCO）和其他各种方法来激活 MOF，同时还提供了最近的实例。之后，我们还从经济角度出发，对 MOF 在实际应用中的未来前景进行了展望。总的来说，我们旨在介绍 MOF 技术的机遇和现状的批判性评价，以及它们的回收/再利用/再生，以考虑其对环境的影响。
