Herein, we report a metal-organic framework featuring a binuclear copper unit, showing extraordinarily high catalytic activity (102.8 mmol g-1 h-1) for photodriven hydrogen generation, which is attributed to the synergistic catalytic effect between the two copper ions.

Effective degradation and detoxification of the highly toxic organophosphate pesticide methyl parathion (MP) are important for pollution treatment and sustainable development. Enzymatic hydrolysis of MP by organophosphate hydrolase (OPH) is an effective way. However, hydrolytic product 4-nitrophenol (4-NP) remains environmentally hazardous.

ConspectusMolecular photochemistry, by harnessing the excited states of organic molecules, provides a platform fundamentally distinct from thermochemistry for generating reactive open-shell or spin-active species under mild conditions. Among its diverse applications, the resurgence of the Minisci-type reaction, a transformation historically reliant on thermally initiated radical conditions, has been fueled by modern photochemical strategies with improved efficiency and selectivity. Consequently, the photochemical Minisci-type reaction ranks among the most enabling methods for C()-H functionalizations of heteroarenes, which are of particular significance in medicinal chemistry for the rapid diversification of bioactive scaffolds.

The nanoscale environment within the void spaces of metal-organic frameworks (MOFs) can significantly influence the photoredox catalytic activity of encapsulated visible-light photoredox catalysts (PCs). To compare two isostructural PC@In-MOF systems, three cationic Ru(II) polypyridine complexes were successfully encapsulated within the mesoscale channels of the anionic framework of InTATB (HTATB = 4,4',4''--triazine-2,4,6-triyltribenzoic acid), which features a doubly interpenetrated framework structure. This encapsulation yielded three heterogenized visible-light PCs, RuL@InTATB, where L = 2,2'-bipyridine (bpy), 1,10-phenanthroline (phen), or 2,2'-bipyrazine (bpz).

In this work, a novel organic heterojunction of polydopamine (PDA)@covalent organic framework (COF) was efficiently synthesized the sonochemical method, leveraging the multifunctional properties of PDA as nucleation sites for COF shell (sonoTp-TAPB) growth. The as-prepared PDA@sonoTp-TAPB hierarchical structure delivers a photocatalytic HO production rate of 728.4 μmol g h in pure water.

Lithium-sulfur batteries (LSBs) hold great potential as next-generation energy storage systems due to their high theoretical energy density and relatively low cost. However, their practical application is hindered by issues such as the shuttle phenomenon caused by soluble lithium polysulfides (LiPSs), slow redox reaction rates, and unsatisfactory cycling stability. In this study, novel conjugated metal-organic frameworks, MM″(HHTP) (M, M″ = Ni, Co, Cu) is reported, as a functional coating on polypropylene (PP) separators.
