摘　　要：氧基氯化铁(FeOCl)是一种典型的Fe基层状材料,于20世纪30年代被发现,并于20世纪70年代起作为一种优异的插层主体在超分子插层化学领域进行了大量的研究。FeOCl的层状结构赋予了其远比传统铁(氢)氧化物更加灵活的调变空间,自2013年第一次发现FeOCl具有优异的固体Fenton活性以来,围绕FeOCl及其插层化合物在催化、能源等领域涌现了大量的应用性研究,展现了其巨大的发展潜力。本文首先对FeOCl及其几种典型的插层体系进行了介绍,重点对插层诱导的FeOCl晶体和电子结构变化进行了讨论,然后对FeOCl及其插层化合物在水中污染物高级氧化降解、电极材料以及其他新兴领域的应用研究进展进行了综述。最后,从FeOCl的结构设计和稳定性等方面对其未来的开发应用趋势进行了展望。Iron oxychloride(FeOCl)is a typical iron-based material with layered structure.It was discovered in the 1930 s,and since the 1970 s,has been extensively studied as a unique host in the field of supramolecular intercalation chemistry.The modification of FeOCl is much more flexible and easier than traditional iron(hydr)oxides due to the layered structure.In 2013,our group reported that FeOCl has excellent Fenton-like activity,which shows the promising potentialities for practical applications.Inspired by the properties of FeOCl and encouraged by our result,FeOCl and its intercalation compounds have recently attracted significant attention in catalysis and energy storage.In this review,the characteristics of pristine FeOCl and its intercalation compounds are summarized,especially intercalation-induced crystal and electronic structure changes.And then we focus on the contributions made by these materials toward advanced oxidation processes(AOPs),selective oxidation,electrode materials and other fields.Finally,challenges and future perspectives are reviewed in terms of structural design and the improvement of stability.
