利用绿色和可持续的太阳能，通过光催化被认为是解决日益严重的能源短缺和环境恶化的一个有前途的策略。除了传统的半导体基光催化剂外，金属有机骨架（MOFs）是一类由金属或金属节点与多齿状有机连接剂相互连接而成的晶体微介孔杂化材料，是一种新型的光催化材料。MOF的合成后修饰（Post-synthetic modification， PSM），即在预先合成的MOF材料上进行化学转化或交换，是在现有MOF的基础上制备光活性MOF的一种有效策略。本文综述了光活性mof的不同PSM策略，包括不饱和金属位配位、开放配位金属化、配体共价修饰、配体交换、金属交换和空腔封装。最后对PSM光催化mof的发展方向和面临的挑战提出了看法。我们希望这篇前沿文章能够为通过PSM策略合理设计高效mof基光催化剂提供一些指导，并激发更多的研究兴趣，致力于这一前景广阔但尚未开发的领域。
The utilization of green and sustainable solar energy via photocatalysis is regarded as a promising strategy to tackle the ever-increasing energy shortage and environmental deterioration. In addition to traditional semiconductor-based photocatalysts, metal-organic frameworks (MOFs), a class of crystalline micro-mesoporous hybrid materials constructed from metal or metal nodes interconnected with multi-dentate organic linkers, are emerging as a new type of photocatalytic material. Post-synthetic modifications (PSM) on MOFs, in which chemical transformations or exchanges are made on pre-synthesized MOF materials, are found to be a powerful strategy for fabricating photoactive MOFs based on already existing MOFs. In this frontier article, different PSM strategies for the development of photoactive MOFs, including coordination on unsaturated metal sites, metalation on open coordinated sites, covalent modifications on ligands, ligand exchange, metal exchange and cavity encapsulation, have been summarized. Our views on the challenges and the direction in developing photocatalytic MOFs by PSM are also addressed. We hope that this frontier article can provide some guidance for rational designing of highly efficient MOF-based photocatalysts via PSM strategies and to stimulate more research interest to be devoted to this promising yet largely unexplored field.
