Ultrahigh Proton/Vanadium Selective and Durable Nafion/TiZrO₄ Composite Membrane for High-Performance All-Vanadium Redox Flow Batteries

A single-phase TiZrO4 nanotube (TiZrO4NT)-incorporated Nafion composite membrane with ultrahigh ion selectivity is designed and fabricated for vanadium redox flow batteries (VFBs). A single cell of the VFB using the potential Nafion/TiZrO4NT composite membrane shows high-capacity retention, low self-discharge rate, and high cycling efficiency. Furthermore, an excellent proton conductivity of 75.9 mS cm–1 at room temperature and 23-fold higher H+/VO2+ selectivity (3.61 × 106 S min cm–3) are obtained for the Nafion/TiZrO4NT composite membrane compared with a state-of-the-art Nafion-212 membrane (55.4 mS cm–1 and 0.168 × 106 S min cm–3). Subsequently, a high VFB performance is achieved with 1.7-fold higher discharge capacity and impressive cycling Coulombic efficiency (CE, 99.8%), voltage efficiency (VE, 84.1%), and energy efficiency (EE, 83.9%) using the Nafion/TiZrO4NT composite membrane than those of the Nafion-212 membrane (CE, 89.9%; VE, 81.2%; and EE, 72.9%). Moreover, the low area resistance of the membrane, high-rate capability, excellent battery durability of 300 charge–discharge cycles, and high self-discharge time ensure the incorporation of the TiZrO4NT filler into the Nafion matrix and improve the selectivity of the fabricated Nafion/TiZrO4NT composite membrane. Consequently, the Nafion/TiZrO4NT composite membrane with ultrahigh ion-selectivity and superior battery performance is considered a potential candidate for high-performance VFBs

A Nanocatalyst-Based Assay for Proteins: DNA-Free Ultrasensitive Electrochemical Detection Using Catalytic Reduction of <i>p</i>-Nitrophenol by Gold-Nanoparticle Labels

This communication reports a nanocatalyst-based electrochemical assay for proteins. Ultrasensitive detection has been achieved by signal amplification combined with noise reduction:  the signal is amplified both by the catalytic reduction of p-nitrophenol to p-aminophenol by gold-nanocatalyst labels and by the chemical reduction of p-quinone imine to p-aminophenol by NaBH4; the noise is reduced by employing an indium tin oxide electrode modified with a ferrocenyl-tethered dendrimer and a hydrophilic immunosensing layer

Engineered Tubular Nanocomposite Electrocatalysts Based on CuS for High-Performance, Durable Glucose Fuel Cells and Their Stack

Exploring the electrochemically active and robust nanocatalysts for the efficient glucose oxidation reaction (GOR) and oxygen reduction reaction (ORR) garners enormous interest in the development of high performance glucose fuel cells (GFCs). The bifunctional copper sulfide (CuS) nanotubes and their specific surface engineering modification with nickel hydroxide (Ni­(OH)₂) and manganese dioxide (MnO₂) nanostructures evade the constrains of existing GOR and ORR catalysts, respectively. On the basis of a systematic electrochemical analysis, the fundamental intrigue on the optimization and influences of core and shell nanostructures toward GFC performances is realized. Under alkaline conditions, CuS@Ni­(OH)₂ and CuS@MnO₂ as GOR and ORR catalysts, respectively, demonstrate the maximum GFC power density of 1.25 mW cm^–2 with 300 h of durability. Furthermore, the energy harvest from a GFC stack without any major performance loss in comparison with a single cell enunciate the excellent energetic capabilities of a stack design. These findings thus provide the compatible solutions for the thriving research areas of GOR and ORR, and by coupling the aforesaid research efforts, high performance and durable GFCs are established

Facile Transfer Hydrogenation of N‑Heteroarenes and Nitroarenes Using Magnetically Recoverable Pd@SPIONs Catalyst

Catalysts with active, selective, and reusable features are desirable for sustainable development. The present investigation involved the synthesis and characterization of bear-surfaced ultrasmall Pd particles (<1 nm) loaded onto the surface of magnetic nanoparticles (8–10 nm). The amount of Pd loading onto the surface of magnetite is recorded as 2.8 wt %. The characterization process covered the utilization of scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), transmission electron microscopy (TEM), inductively coupled plasma (ICP), and X-ray photoelectron spectroscopy (XPS) methods. The Pd@Fe3O4 catalyst has shown remarkable efficacy in the hydrogenation of quinoline, resulting in the production of >99% N-ring hydrogenated (py-THQ) product. Additionally, the catalyst facilitated the conversion of nitroarenes into their corresponding aniline derivatives, where hydrogen was achieved by H2O molecules with the aid of tetrahydroxydiboron (THDB) as an equilibrium supportive at 80 °C in 1 h. The high efficiency of a transfer hydrogenation catalyst is closely related to the metal–support synergistic effect. The broader scope of functional group tolerance is evaluated. The potential mechanism underlying the hydrogenation process has been elucidated through the utilization of isotopic labeling investigations. The application of the heterocyclic compound hydrogenation reaction is extended to formulate the medicinally important tubular polymerization inhibitor drug synthesis. The investigation of the recyclability of Pd@Fe3O4 has been conducted
