Metal-organic frameworks for photocatalysis

The authors report a family of photocatalysts containing Ce active sites and perylene diimide ligands for the aerobic oxidation of substituted toluene, ethylbenzene, benzyl alcohol, thioanisole, and benzylamine in acetonitrile.

Maji and coworkers report the selective conversion of CO₂ to CH₄ under visible light by utilizing a charge transfer complex within Zr-MOF-808 pores. The complex ultimately facilitates efficient multielectron reduction at the Zr-catalytic center.

A crystalline hetero-metallic cluster catalyst based on a covalent organic framework strategy is reported. The catalyst can facilitate both photocatalytic oxidative and reductive reactions leading to efficient production of HCOOH from CO2 and H2O.

Organolead halide hybrids are promising materials but are often unstable under moisture and/or light irradiation. Here, metal-organic frameworks containing lead halide secondary building units are shown to be stable for photocatalytic CO₂ reduction with water vapor.

A Ni-based MOF catalyst is reported to facilitate the photocatalytic reduction of CO2 to CO, a low-value product. In tandem, the as-produced CO is used as a reactant in the Pd-catalyzed carbonylation of aryl halides and other fine organic chemicals.

Heterogeneous electron donor–acceptor (EDA) catalysis has seen limited progress to date. Here, the authors showcase a significant improvement in EDA interaction by employing a metal-organic framework (MOF) as the donor catalyst, underscoring the potential of MOFs in catalytic processes.

In this study, the authors explored the correlation between the structure and optoelectronic properties of metal organic frameworks for the removal of a harmful herbicide from water.

Photoelectrochemical systems have emerged as a sustainable technology for wastewater treatment. Here, Tang et.al report a bias-free driven ion assisted photoelectrochemical system that can utilize sodium chloride in seawater as a cost-effective additive for wastewater treatment.

The regulation of heterogeneous material properties to enhance the peroxymonosulfate activation remains a challenge. Here, authors synthesize S−scheme heterojunction PBA/MoS2@chitosan hydrogel to achieve photoexcitation synergistic peroxymonosulfate activation driven by interface electric field.
