“…24,25 These compounds contain electron-releasing groups and due to their appropriate optical response are considered suitable photocatalysts, that can be used in many relevant applications such as removal of organic pollutants. 26 For instance, MOF-5, 27 UiO-66(Zr), ZIF-8, 28 and MIL-125(Ti) 23 have served as semiconductor photocatalysts. However, such semiconductor MOFs are hardly operative for solar visible light photocatalysis, unless their organic linkers or metal clusters are properly modied.…”

“…The Fourier transform infrared spectroscopy (FT‐IR) spectra of the MOFs@PP separator was carried out to investigate the composite of the membrane (Figure 1g). The peaks at 3438 and 3330 cm −1 were allocated to the symmetric and asymmetric stretching of the NH 2 groups, [ 20 ] while the NH bend vibration and CN stretching vibration of aromatic amine were observed at 1665 and 1258 cm −1 , respectively. [ 21 ] The appearance of the peaks at 1538 and 1380 cm −1 were attributed to the asymmetric and symmetric vibrations of carboxyl groups, respectively.…”

Developing high energy density lithium secondary batteries is pivotal for satisfying the increasing demand in advanced energy storage systems. Lithium metal batteries (LMBs) have attracted growing attention due to their high theoretical capacity, but the lithium dendrites issue severely fetter their real‐world applications. It is found that reducing anion migration near lithium metal prolongs the nucleation time of dendrites, meanwhile, promoting homogeneous lithium deposition suppresses the dendritic growth. Thus, regulating ion transport in LMBs is a feasible and effective strategy for addressing the issues. Based on this, a functional separator is developed to regulate ion transport by utilizing a well‐designed metal‐organic frameworks (MOFs) coating to functionalize polypropylene (PP) separator. The well‐defined intrinsic nanochannels in MOFs and the negatively charged gap channels both restricts the free migration of anions, contributing to a high Li+ transference number of 0.68. Meanwhile, the MOFs coating with uniform porous structure promotes homogeneous lithium deposition. Consequently, a highly‐stable Li plating/stripping cycling for over 150 h is achieved. Furthermore, implementation of the separator enables LMBs with high discharge capacity, prominent rate performance and good capacity retention. This work is anticipated to aid developement of dendrite‐free LMBs by utilizing advanced separators with ion transport management.

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.
