“…Among the most active reported MOF‐based photocatalysts, one should mention a complex Zn‐porphyrin system that uses [Ru(2,2‐pipyridine) 3 ] 2+ centers as photosensitizers and Ir–bipyridine catalytic centers, encapsulated within the hydrophilic interior of a liposome and in the presence of two redox relays: Fe 3+ /Fe 2+ ions (in the aqueous phase) and tetrachlorobenzoquinone (TCBQ)/tetrachlorobenzohydrosemiquinone (TCBQH) pair (in the organic phase), exhibiting a production of 836 µmol g −1 in 72 h under LED light irradiation. [ 46 ] In comparison with this complex multicomponent system, IEF‐11 exhibits higher performance in terms of production (672 µmol g −1 in 22 h vs 836 µmol g −1 in 72 h from the liposome system) and high photocatalytic stability upon reuse (up to 10 d vs unreported reuses). In addition, IEF‐11 is a much simpler photocatalytic system constituted by a single material with lower cost (derived from the absence of expensive noble metals as Ru or Ir that are present in the liposome system).…”

A new porous titanium(IV) squarate metal–organic framework (MOF), denoted as IEF‐11, having a never reported titanium secondary building unit, is successfully synthesized and fully characterized. IEF‐11 not only exhibits a permanent porosity but also an outstanding chemical stability. Further, as a consequence of combining the photoactive Ti(IV) and the electroactive squarate, IEF‐11 presents relevant optoelectronic properties, applied here to the photocatalytic overall water splitting reaction. Remarkably, IEF‐11 as a photocatalyst is able to produce record H2 amounts for MOF‐based materials under simulated sunlight (up to 672 µmol gcatalyst in 22 h) without any activity loss during at least 10 d.

“…Thec erium salt, the free ligand NAD + and their physical mixture were applied in this model experiment, resulting in negative activity under identical conditions (Table 1, entries 4-6), verifying the high photocatalytic activity of Ce-NAD + for the arylation of inert C(sp 3 )ÀHbonds and that the conjunction of NAD + fragments and Ce-OEt moieties was conducive to promoting the PET and LMCT for multiphoton excitation activation of inert C(sp 3 ) À Hbonds. [32] Moreover,the addition of the alkalies into the aforementioned photocatalytic reaction systems did not result in as ignificant enhancement on the yields (Table 1, entries 7a nd 8).…”

The activation and oxidization of inert C(sp 3 )ÀH bonds into value-added chemicals affords attractively economic and ecological benefits as well as central challenge in modern chemistry.I nspired by the natural enzymatic transformation, herein, we report an ew multiphoton excitation approach to activate the inert C(sp 3 ) À Hb onds and oxygen by integrating the photoinduced electron transfer (PET), ligand-to-metal charge transfer (LMCT) and hydrogen atom transfer (HAT) events together into one metal-organic framework. The wellmodified nicotinamide adenine dinucleotide (NAD + )m imics oxidized Ce III -OEt moieties to generate Ce IV -OEt chromophore and its reduced state mimics NADC via PET.The in situ formed Ce IV -OEt moiety triggers aL MCT excitation to form the alkoxy radical EtOC,a bstracts ah ydrogen atom from the C(sp 3 )ÀHb ond, accompanying the recovery of Ce III -OEt and the formation of alkylr adicals.T he formed NADC activates oxygen to regenerate the NAD + for next recycle,w herein, the activated oxygen species interacts with the intermediates for the oxidization functionalization, paving ac atalytic avenue for developing scalable and sustainable synthetic strategy.

Photocatalysis is considered to be a green and environment‐friendly technology since it can convert solar energy into other types of chemical energies. Over the past several years, metal‐organic frameworks (MOFs)‐based photocatalysts have received remarkable research interest due to their unique morphology, high photocatalytic performance, good chemical stability, easy synthesis, and low cost. In this review, the synthetic strategies of developing MOFs‐based photocatalysts are first introduced. Second, the recent progress in the fabrication of various types of MOFs composites photocatalysts is summarized. Third, the different applications including hydrogen evolution reaction, oxygen evolution reaction, overall water splitting, nitrogen reduction reaction, carbon dioxide reduction reaction as well as photodegradation of organic pollutants of MOFs‐based photocatalysts are summed up. Finally, the challenges and some suggestions for the future development of MOFs‐ and their composites‐based photocatalysts are also highlighted. It is expected that this report will help researchers to systematically devise and develop highly efficient photocatalysts based on MOFs and their composites.
