The composite materials were comprehensively characterized, and their performance in the electrochemical CO2 reduction reaction (CO2RR) was systematically evaluated. The Cu@CTFs exhibited significant enhancements in CO2RR performance compared to their unmodified counterparts. The as-synthesized Cu@CC-BP-CTF electrocatalyst possessed exceptional catalytic efficiency due to its highly porous structure and great surface area. At a voltage of 1.6 V versus RHE, it achieved a maximum CO Faradaic efficiency of 39%. In addition, the activity of this system was characterized by a partial current density of around 85.8 mAcm-2 in a flow-cell configuration. Furthermore, this catalyst demonstrated remarkable stability over 10 h, highlighting its significant potential for real-world utilization in CO2RR. The Cu@CC-BP-CTF electrode exhibited superior CO2RR activity, higher mass activity, and improved charge transfer rates incomparable to the unmodified counterpart. These findings highlight the crucial role of copper in modifying the surface properties of electrocatalysts, providing valuable insights into the design strategies for advanced materials with enhanced performance in electrochemical applications.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e70292"},"PeriodicalIF":3.3,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145063054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, most electronic devices run on a lithium-ion battery (LIB). However, safety issues prompt researchers to consider alternatives, and the aqueous zinc-ion battery (AZIB) emerged as an alternative with higher merits. One of the fundamental segments of the AZIB is the separator that provides ion transportation on both sides of the battery while deterring direct contact between the cathode and anode. For AZIBs, glass fiber (GF) is the most conventional separator considering their availability and cost-effectiveness, suffering from various hurdles, for instance, dendrite formation, which is the primary concern, causing an explosion during battery operation, and the low mechanical strength. Conversely, the polyacrylonitrile (PAN) prevents dendrite formation through the electrostatic interaction, deposition along the (002) plane, 3D diffusion, and selective zinc ion permeation, and offers high cyclability. We segment this paper into four parts: first, it discusses the basic features of the ideal separator; second, the preparation methods of the separator; third, a critical overview of the PAN-based separator for AZIB, especially the dendrite mitigation strategies; and finally, it provides the future directions and strategies for advance PAN-based separator design.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e00810"},"PeriodicalIF":3.3,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145063057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fluorescence titration studies revealed remarkable selectivity and reversible binding affinity of TREN-Nap toward Cu(II) ions, with significant enhancement (turn-on) in fluorescence emission intensity and sensitivity at the micromolar level (0.74 µM, 0.24 ppm). Notably, similar titration studies with other commonly interfering metal cations such as Zn(II), Mg(II), Cd(II), Ni(II), Co(II), Ba(II), Al(III), Pb(II), and Ca(II) caused almost negligible changes in the emission intensity, indicating their weak binding with TREN-Nap.

Herein, we utilized cellulose extracted from waste date palm trees (DPT) and Nafion to fabricate an in-house membrane that contributes to mitigating this problem. A series of Nafion membranes with cellulose ratios of 5, 10, 20, and 30 wt% were fabricated and labeled CNF5, CNF10, CNF20, and CNF30, respectively. The CNF20 displayed promising thickness (∼77 µm) and mechanical stability, and as a result, it was investigated further and compared with the commercial Nafion 117 membrane. CNF20 exhibited an ion exchange capacity of 1.35 meq/g, water uptake of 39% and ionic conductivity of 0.090 S/cm. Both membranes exhibited a charge capacity of approximately 555.5 mAh/L. However, CNF20 retained 99.9% of its capacity, as compared to 93.7% for Nafion 117, after 100 cycles. The charge capacity decay and discharge capacity decay for CNF20 were 18 times and 120.6 times lower, respectively, than for the Nafion 117 membrane. The CNF20 showed energy efficiency of 31.3% whereas Nafion 117 exhibited 23.2% over 100 cycles. The cost analysis for CNF20 resulted in a 57.7% reduction as compared to the commercial price of Nafion 117.

The introduction of the arms to the dipyrromethane moieties not only make them polyfunctional but also enhances flexibility of the system. In this review article, we highlight the syntheses and metal-ion coordination of various donor-extended meso-disubstituted dipyrromethane-based ligands that include the scaffolds decorated with diamine, diimine, bis-azo, diphosphine, or bis-pyrazole functions on both sides. The resulting NNNN and PNNP types of tetradentate dipodal ligands yield a large number of transition or alkali metal complexes with attractive structural and coordination properties, expressing the main focus of this article. We also emphasize the structural variations of the complexes dictated by the steric-bulk of the substituents at the meso-position or at the termini of the dipods. In addition, certain metal complexes bearing the extended ligand(s) participate in distinct catalytic transformations and also show interesting magnetic behaviors that are minutely discussed.
