“…X-ray powder diffraction (XRD) was applied to evaluate the crystallinity of CC@UiO-66(SH) 2 . As shown in Figure a, the XRD pattern of CC@UiO-66(SH) 2 displays two sharp peaks at 2θ = 7.36° and 8.48° and a broad peak at 2θ = 26.24°, corresponding to the (110) and (200) planes of UiO-66(SH) 2 and a hexagonal graphite structure of CC, indicative of successful decoration of the crystalline UiO-66(SH) 2 nanoparticles on CC . It can be seen from Figure S4 that CC@UiO-66 exhibits a similar XRD pattern as CC@UiO-66(SH) 2 .…”

Lithium–sulfur (Li–S) batteries hold great promise for new-generation energy storage technologies owing to their overwhelming energy density. However, the poor conductivity of active sulfur and the shuttle effect limit their widespread use. Herein, a carbon cloth decorated with thiol-containing UiO-66 nanoparticles (CC@UiO-66(SH)2) was developed to substitute the traditional interlayer and current collector for Li–S batteries. One side of CC@UiO-66(SH)2 acts as a current collector to load active materials, while the other side serves as an interlayer to further restrain polysulfide shuttling. This two-in-one integrated architecture endows the sulfur cathode with fast electron/ion transport and efficient chemical confinement of polysulfides. More importantly, rich thiol groups in the pores of UiO-66(SH)2 serve to tether polysulfides by both covalent interactions and lithium bonding. Therefore, the Li–S battery equipped with this integrated interlayer–current collector not only delivers an enhanced specific capability (1209 mAh g–1 at 0.1 C) but also exhibits prominent cycling stability (an attenuation rate of 0.037% per cycle for 1000 cycles at 1 C). Meanwhile, the battery achieves a high discharge capacity of 795 mAh g–1 at a sulfur loading of 3.83 mg cm–2. The new metal–organic framework (MOF)-based electrode material reported in this study undoubtedly provides insights into the exploration of functional MOFs for robust Li–S batteries.

“…Carbon materials like graphene and carbon nanotubes (CNTs) with unique properties have attracted numerous attention as foreign components in MOF‐based composite photocatalysts, due to their ability to facilitate the transfer of electrons and suppress the recombination of photogenerated electron–hole pairs [77a,94] . Moreover, strong interactions, such as π–π interaction, between the graphene layer and 2D MOLs could be realized, which further promote the charge transfer between the two components.…”

Photocatalytic carbon dioxide (CO2) reduction can utilize solar light to convert CO2 to high value‐added products, which thus are recognized as an intriguing strategy to solve excessive CO2 emissions. Metal–organic framework (MOF)‐based photocatalysts have shown high potential in the field of CO2 reduction due to their high porosity and tunable structure. In this review, the recent progress achieved in the rational design of MOF‐based photocatalysts, including the pure MOF materials, MOF‐based composites, and the derivatives of MOFs, for the reduction of CO2, are summarized and the developed modification strategies to enhance the photocatalytic performance of MOF‐based photocatalysts are highlighted. The current pending issues and the outlook for the future development are also discussed.

“…Wang et al fabricated hierarchically heterostructured UIO‐66‐NH 2 /CNTs ( Figure a) that exhibited high selectivity for HCOOH generation. [ 128 ] Scanning electron microscopy (SEM) images showed that UIO‐66‐NH 2 particles were uniformly grown on the surface of the CNTs, as shown in Figure 21b,d. The uniform loading of UIO‐66‐NH 2 particles may enhance the multiple reflections between the crystals, which is conducive to the conduction of electrons.…”

As one of the most outstanding allotropes of carbon assembled with a cylindrical nanostructure, carbon nanotubes (CNTs) have attracted extensive attention in the areas of material science and engineering due to their unique structural characteristics and physicochemical properties. Very recently, versatile hierarchical CNT‐based photocatalysts are of considerable interest in current research and applications ranging from fuel generation to environmental purification. Therefore, it is necessary to summarize the CNT‐based photocatalysts to provide essential references for the continuous research study. In this review, the different design strategies and flexible functionalizations for prototype construction are described and their typical research, especially the structure‐related or electronic‐effected mechanism in the photocatalytic reaction of pollutants degradation, water splitting, and CO2 reduction overviewed. Finally, the various aspects of CNT‐based photocatalysts are discussed for future developments in commercial applications.
