A multifunctional antifouling sustainable membrane was developed by integrating MIL-125(Ti) and carboxylated cellulose nanofibers (CCNF) into a PVDF matrix via non-solvent induced phase separation. The resulting membrane exhibited high water flux (up to 410 L·m⁻²·h⁻¹·bar⁻¹), excellent dye rejection (>97% for MB, CV, MG), strong self-cleaning ability, and outstanding antifouling stability (FRR >94%). This work offers a green, efficient strategy for next-generation water treatment membranes combining physical separation and photocatalytic degradation.

Transition metal dichalcogenides, particularly molybdenum disulfide (MoS2), are gaining attention for their abundant resources, low cost, and high catalytic activity. However, challenges such as agglomeration, poor electrical conductivity, and low active site density limit their use in hydrogen evolution reactions (HER). This study presents a flexible self-supporting catalytic electrode, C@MoSx@pCNF, developed through potassium electrochemical intercalation. This method fragments the MoS2 nanosheets encapsulated in conductive carbon into smaller lamellas, transforming them into an amorphous structure. Compared to crystalline MoS2, the amorphous MoSx exhibits increased active sites and enhanced superhydrophilic and superhydrophobic properties. Under acidic conditions, the C@MoSx@pCNF electrode shows a low overpotential of 51 mV at a current density of 10 mA cm-2 with a Tafel slope of 77 mV dec-1, highlighting its exceptional HER performance and providing a new approach to enhance the catalytic efficiency of MoS2.
过渡金属二硫化物，特别是二硫化钼（MoS2）因其资源丰富、成本低、催化活性高等特点而日益受到人们的关注。然而，诸如团聚、导电性差和低活性位点密度等挑战限制了它们在析氢反应（HER）中的应用。本研究提出了一种柔性自支撑催化电极C@MoSx@pCNF，该电极是通过钾电化学插层制备的。这种方法将包裹在导电碳中的二硫化钼纳米片分解成更小的片层，将其转化为非晶结构。与结晶MoS2相比，无定形MoSx表现出活性位点增加，超亲水性和超疏水性增强。在酸性条件下，C@MoSx@pCNF电极在电流密度为10 mA cm-2、Tafel斜率为77 mV dec1时的过电位为51 mV，突出了其优异的HER性能，为提高MoS2的催化效率提供了新的途径。

We have engineered heterogeneous asymmetric sites at Eu2O3/CuO interface to enhance the methane formation pathway during CO2 electroreduction, where Cu2+ species can stabilize the crucial *CO intermediate, whereas Eu3+ sites facilitate the hydrogenation of *CO by supplying more reactive *H species. Consequently, the Eu2O3/CuO heterostructure attains a remarkable Faradaic efficiency up to of 63.1% for methane production.

The significant highlight of this method is the production of greener byproducts. Remarkably, the developed method is promising in accessing drugs like butamben and benzocaine and other potential pharmaceutical precursors. The current protocol is highly functional group tolerant and also scalable to gram-scale synthesis. Density functional theory calculations have been performed with control studies to comprehend the mechanistic pathways.

The conversion of carbon dioxide (CO2) into value-added chemicals offers a promising path for greenhouse gase utilization. Porous organic cages (POCs), an emerging subclass of porous materials, have shown great potential in catalysis, primarily as catalyst supports and stabilizers for metal nanoparticles (MNPs) to enhance their catalytic activity. Herein, we report the use of an ionic POC (OFT-RCC36+6Br−) as a metal-free catalyst for the cycloaddition of CO2 and epoxides, generating cyclic carbonates in high yields. This POC catalyst is highly efficient, achieving a maxmium yield of up to 90% with a turnover number (TON) of 3000 without requiring reaction solvents. Moreover, with the synergistic effect of 1,8-Diazabicyclo [5.4.0]undec-7-ene (DBU), the catalytic performance can be further enhanced across a wide substrate range.

Boramidine is a small water-soluble organic fluorophore that was recently introduced as a versatile building block of fluorescent probes. Herein, we show that boramidine is protonated in highly protic solvents. This behaviour explains the surprisingly large difference in the absorption spectrum reported previously when going from an organic to an aqueous environment. Transient absorption measurements reveal that the invariance of the fluorescence spectrum to the environment arises from an excited-state proton transfer to the solvent occurring a few ps after photoexcitation of the protonated boramidine. This photoacidity of boramidine is a further add-on to the polyvalence of this fluorophore.
