Titanium (Ti)‐based metal–organic frameworks (MOFs) have attracted intensive attention due to the low toxicity, high earth's crust abundance, and unique photocatalytic properties of Ti elements. Great efforts have been devoted to the synthesis of novel architectures and their potential applications involving photocatalysis. However, Ti‐MOFs are still very scarce owing to their challenges in controlling the Ti chemistry in the reaction system. Until now, some significant results have been achieved, which may shed new insight into the future investigation of Ti‐MOFs. Herein, some representative researches in Ti‐MOFs are summarized and reviewed from the following four aspects: first, various synthetic strategies for preparing Ti‐MOFs are introduced; second, diverse structures containing multi‐connected ligands are presented in detail; third, the potential photocatalytic applications of Ti‐based MOFs involving H₂ production, CO₂ reduction, H₂O₂ production, N₂ fixation, remediation of organic and inorganic pollutants, as well as organic transformation reaction and photocatalytic sensors are discussed; finally, perspectives on current challenges and emerging opportunities in this research field are discussed. Through summarizing this specific type of MOF, this review is expected to stimulate researchers’ interest for in‐depth investigation of novel structures synthesis, as well as new applications and concepts in these intriguing fields.

钛基MOF材料：从晶体工程到光催化

钛（Ti）基金属有机骨架（MOF）由于其低毒性，高地壳丰度和独特的光催化性能而受到了广泛的关注。已经致力于合成新型结构及其涉及光催化的潜在应用。但是，由于Ti-MOF在控制反应体系中的钛化学方面面临挑战，因此仍然非常稀缺。到目前为止，已经取得了一些重大成果，这可能为Ti-MOF的未来研究提供了新的见识。本文从以下四个方面对Ti-MOFs的一些代表性研究进行了总结和综述：首先，介绍了制备Ti-MOFs的各种合成策略。其次，详细介绍了包含多连接配体的各种结构。第三，_{讨论了2的}产生，CO _2的还原，H ₂ O _2的产生，N _2的固定，有机和无机污染物的修复以及有机转化反应和光催化传感器；最后，讨论了该研究领域中当前挑战和新兴机遇的观点。通过总结这种特定类型的MOF，该综述有望激发研究人员对新颖结构合成以及这些有趣领域中的新应用和概念进行深入研究的兴趣。
