Titanium-based metal organic frameworks (Ti-MOFs) have become a hot topic in current materials research due to their excellent photocatalytic activity. However, due to the extremely high reactivity and oxygenophilic properties of Ti ions, oxides and other competing by-products are easily formed during the reaction process, making the synthesis of Ti-MOFs extremely challenging. The research on Ti-MOFs was carried out simultaneously at the early stage of MOFs development, however, after more than two decades of development, only tens of Ti-MOFs have been reported, accounting for an extremely limited proportion of the tens of thousands of MOFs. In order to avoid or reduce the occurrence of titanium ion side reactions, Ti-MOFs are usually synthesized by introducing metal Ti ions into the framework of known MOFs to orientate the synthesis of Ti-MOFs, which is called post-synthetic method (PSM) and is also an effective method to construct Ti-MOF framework. The examples of PSM for constructing Ti-MOFs are systematically investigated and summarized in a timely manner. Firstly, based on the different ways and positions of titanium ion introduction, three routes are classified as ion exchange, ion insertion (introduction of titanium ion at the position of metal nodes or cluster units) and ligand modification (introduction of titanium ion at the position of organic ligands), and the Ti-MOFs constructed by each route are introduced by examples. Subsequently, the design and application of Ti-MOFs constructed by PSM and their composites are discussed. Finally, the current status of PSM-constructed Ti-MOFs is summarized and the future development direction is foreseen.
