“…As compared, the Ag/AgBr@UiO‐66‐40 demonstrates the removal efficiency of 82.1 %. And, compared with the reported other photocatalyst of AgX@MOF, Ag/AgBr@UiO‐66‐NH 2 showed much superior photocatalytic ability (Table S1, Supporting Information), i.e. the amount of degraded dyes per gram catalyst.…”

Porous metal‐organic frameworks (MOFs) loading metal nanoparticles to form a composite photocatalyst demonstrated unique advantages. Modification of the electron donating group on the aromatic linkers of MOFs could increase the absorption range of light, thereby increasing the photocatalytic activity. In this study, we prepared a composite photocatalyst using a stable NH2‐functionalized MOF (UiO‐66‐NH2) to load semiconductor Ag/AgBr nanoparticles, and the resultant composites have intense optical absorption throughout visible light range. The greatly enhanced optical absorption and the unique hetero‐junction between Ag/AgBr and UiO‐66‐NH2 render efficient separation and utilization of photogenerated electron‐hole pairs. Therefore, Ag/AgBr@UiO‐66‐NH2 showed much more excellent photocatalytic activity, compared with unmodified UiO‐66 loading Ag/AgBr (Ag/AgBr@UiO‐66) and reported AgX@MOF catalysts. Moreover, the composite photocatalysts showed excellent stability during cycling experiment.

“…Nevertheless, in some cases the stability of these hybrids is not strong enough. For instance, Ag/AgCl/MIL-53 exhibited high photocatalytic activity for the removal of different dyes, but its efficiency decreased after several recycles [219]. 1 RhB = rhodamine B; MB = methylene blue; PBS = ponceau BS.…”

This review analyzes the preparation and characterization of metal organic frameworks (MOFs) and their application as photocatalysts for water purification. The study begins by highlighting the problem of water scarcity and the different solutions for purification, including photocatalysis with semiconductors, such as MOFs. It also describes the different methodologies that can be used for the synthesis of MOFs, paying attention to the purification and activation steps. The characterization of MOFs and the different approaches that can be followed to learn the photocatalytic processes are also detailed. Finally, the work reviews literature focused on the degradation of contaminants from water using MOF-based photocatalysts under light irradiation.

“…We further explored the detailed degradation mechanism of RhB.N umerous studies have shown that RhB can be efficiently degraded by highly oxidative species (COH, CO 2 À ,a nd hole h + ). [17] Radical trapping experiments and electron spin resonance spectroscopy (ESR) were carried out to detect the roles of possible active species in the photocatalytic process.T he degradation ratio of RhB decreased to 40.1 and 45.3 %a fter adding EDTA-2Na (hole scavenger) and BQ (superoxide radical scavenger), respectively,w hereas weak inhibition was observed after adding TBA( hydroxyl radical scavenger;F igure 5i). Furthermore,E SR experiments were conducted to identify the radicals generated in the photocatalytic process (Figure 5h).…”

Gold clusters loaded on various supports have been widely used in the fields of energy and biology. However, the poor photostability of Au clusters on support interfaces under prolonged illumination usually results in loss of catalytic performance. Covalent organic frameworks (COFs) with periodic and ultrasmall pore structures are ideal supports for dispersing and stabilizing Au clusters, although it is difficult to encapsulate Au clusters in the ultrasmall pores. In this study, a two‐dimensional (2D) COF modified with thiol chains in its pores was prepared. With −SH groups as nucleation sites, Au nanoclusters (NCs) could grow in situ within the COF. The ultrasmall pores of the COF and the strong S−Au binding energy combine to improve the dispersibility of Au NCs under prolonged light illumination. Interestingly, Au–S–COF bridging as observed in this artificial Z‐scheme photocatalytic system is deemed to be an ideal means to increase charge‐separation efficiency.
