Metal-organic frameworks (MOFs)-mediated photocatalysis provides a promising solution to energy shortage and environmental pollution. In the past few years, a large number of modification strategies for improving the photocatalytic performance of MOFs have been developed. Correspondingly, many profound photocatalytic mechanisms, such as the excitonic effect, have been proposed. The newly revealed excitonic effect plays a significant role in the formation of reactive species via either charge transfer or energy transfer. Thus, an up-to-date understanding of MOFs-mediated photocatalysis with the excitonic effect is highly needed. In this work, the excitonic effects in charge transfer and energy transfer processes were critically reviewed for the first time, covering a summary of common techniques for characterizing excitonic effect and mainstream strategies for regulating excitonic behaviors. In addition, the current challenges and future perspectives of MOFs-mediated photocatalysis for energy conversion and environmental remediation were discussed.

MOFs 介导的光催化中的激子效应:现象、表征技术和调控策略

金属有机框架(MOFs)介导的光催化为解决能源短缺和环境污染提供了一个有前途的解决方案。在过去的几年中,已经开发了大量改进 MOFs 光催化性能的修饰策略。相应地,已经提出了许多深刻的光催化机制,例如激子效应。新发现的激子效应在通过电荷转移或能量转移形成活性物质方面起着重要作用。因此,非常需要对 MOFs 介导的具有激子效应的光催化的最新了解。在这项工作中,首次对电荷转移和能量转移过程中的激子效应进行了严格审查,涵盖表征激子效应的常用技术和调节激子行为的主流策略的总结。此外,还讨论了 MOFs 介导的光催化用于能量转换和环境修复的当前挑战和未来前景。
