It is very appealing that 5-hydroxymethylfurfural(HMF)is electrocatalytical oxidized as 2,5-furandicarboxylic acid(FDCA)linking to non-classical cathodic hydrogen(H_(2))***,the electrocatalysts for electrocatalytic HMF oxidative reaction(e-HMFOR)have been facing low Faradaic efficiency(FE)and high water splitting ***,we propose a strategy of the NiSeO_(3)@(CoSeO_(3))_(4)heterojunction by constructing a Co-Ni paired site,where the Co site is in charge of adsorbing for HMF while the electrons are transferred to the Ni site,thus giving the NiSeO_(3)@(CoSeO_(3))_(4)heterojunction superior electrocata lytic performances for e-HMFOR and water *** optimizing conditions,the NiSeO_(3)@(CoSeO_(3))_(4)heterojunction has high conversion of 99.7%,high selectivity of 99.9%,and high FE of 98.4%at 1.3 V,as well as low cell voltage of 1.31 V at 10 mA cm^(-2)in 1 M KOH+0.1 M *** study offers a potential insight for e-HMFOR to high value-added FDCA coupling water splitting to produce H_(2)in an economical manner.

Chinese Journal of chemical engineering 2025年 81卷 45-56页

Two dimensional (2D) membranes show huge potential for ion sieving applications owing to their regular sub-nanometer channels. How to engineer the channel micro-chemistry to pursue higher ion selectivity while maintaining promising ion transports remains challenging. In this work, we propose building rigidly confined charged 2D graphene oxide (GO) channels and manipulating their hydrophilicity via self-designed poly(ionic liquid)s (PILs) intercalation. The imidazolium cations on the PILs backbone not only stabilize the GO interlayer channels via non-covalent interactions but also create a positively charged environment for attracting anions entering into channels. The hydrophilicity variations of the side chains on the PILs help with realizing the regulation of the channel hydrophilicity. Under the electrodialysis mode, the GO membrane with the strongest hydrophobicity yields an impressive selectivity of 172.2 for Cl− and SO42−, which is 48 times of Neosepta ACS, a commercial membrane specialized for anion separation. This work offers a brand-new route in exploring high-performance ion selective membranes. © 2025 chemical Industry and engineering Society of China, and chemical Industry Press Co., Ltd.

Recent developments in chirality chemistry have revealed remarkable instances of atropisomers featuring multiple chiral elements. Despite significant progress in the synthesis and application of atropisomers, developing a synthetic protocol for the simultaneous introduction of axial and point chirality is still a fascinating challenge. In this context, we present a convenient and versatile method for synthesizing novel atropisomers with axial and point chirality. This approach, based on a new reaction mechanism with nickel-controlled Si–C bond activation, facilitates the controllable migratory insertion of aldehydes into the Ni–C bond. We utilize multidimensional strategies of desymmetrization, kinetic resolution and dynamic kinetic resolution to complete enantioselective nickel-catalyzed ring expansion of benzosilacyclobutenes with aldehydes. The design of multidimensional kinetic resolution, desymmetrization, and dynamic resolution, features a straightforward catalytic system, mild reaction conditions, and broad functional group tolerances. Various axially chiral biaryl oxasilacycles bearing carbon-or siliconstereogenic centers are obtained with excellent diastereo-and enantio-selectivities(up to >20:1 dr and >99.9% ee) through the use of a chiral Ni complex with a large cavity-type 1,1,4,4-tetra-aryl-2,3-O-isopropylidene-L-threitol(TADDOL)-derived phosphoramidite ligand.

Alzheimer's disease(AD) is a devastating neurodegenerative disease that affects ～50 million people globally. The accumulation of amyloid-β(Aβ) plaques, a predominant pathological feature of AD, plays a crucial role in AD pathogenesis. In this respect, Aβ has been regarded as a highly promising therapeutic target for AD treatment. Polyoxometalates(POMs) are a novel class of metallodrugs being developed as modulators of Aβ aggregation, owing to their negative charge, polarity, and three-dimensional *** traditional discrete inorganic complexes, POMs contain tens to hundreds of metal atoms,showcasing remarkable tunability and diversity in nuclearities, sizes, and shapes. The easily adjustable and structurally variable nature of POMs allows for their favorable interactions with Aβ. This mini-review presents a balanced overview of recent progress in using POMs to mitigate amyloidosis. Clear correlations between anti-amyloid activities and structural features of POMs are also elaborated in detail. Finally, we discuss the current challenges and future prospects of POMs in combating AD.

The design of novel signal amplification elements was key to improving the sensing and analysis performance of electrochemical sensors. In this work, porous one-dimensional copper nitrogen-doped carbon nanofibers(CuNCNFs) were successfully prepared via the coupled process of electrospinning technology and high-temperature pyrolysis. This coupling of multiple processes and the introduction of heteroatoms pyrolyzed the HKUST-1 particles to generate three-dimensional Cu-doped carbon octahedra and mosaic them inside the one-dimensional carbon nitride channels, obtaining small-sized Cu particles while introducing a large number of N species, and constructing a three-dimensional MOFs-derived metal-carbon hybrid one-dimensional multistage carbon nitride structure. The resulting Cu-NCNFs sensor could simultaneously determine acetaminophen and sulfanilamide and exhibit superior electroanalytical performance, reproducibility, stability, and selectivity. This strategy provides a new approach to preparing novel signal amplification elements for the efficient monitoring of micropollutants.
