Abstract The practical application of room temperature sodium–sulfur (RT Na–S) batteries are prevented by the sulfur insulation, severe shuttling effect high‐order sodium polysulfides (Na 2 S n , 4 ≤ 8), and sluggish reaction kinetics. Therefore, designing an ideal host material to suppress shuttle process accelerate redox reactions soluble NaPSs Na /Na is paramount importance for RT Na–S batteries. Here, a quasi‐solid‐state transformation realized building high efficiency MoC‐W C heterostructure in freestanding multichannel carbon nanofibers via electrospinning calcination methods (MoC‐W C‐MCNFs). interlinked micro‐mesoporous structures that can accommodate volume change electrode materials confine entire (restraining process). Meanwhile, with abundant heterointerfaces facilitate electron/ion transport conversion NaPSs. Consequently, S/MoC‐W C‐MCNFs cathode delivers capacity 640 mAh g −1 after 500 cycles at 0.2 A excellent reversible performance 200 ultralong 3500 . What's more, catalytic mechanism (a transformation) proposed confirmed carbonate electrolyte combining experimentally theoretically.

Spatial confinement of organic pollutants and reactive oxygen species (e.g., SO4•– •OH) with ultrashort lifetime inside the scale chemical theoretical diffusion could provide a greatly promising strategy to overcome limitation mass transfer in heterogeneous Fenton-like oxidation process. Herein, we first reported spatial cobalt nanoparticles N-doped carbon nanorods (Co-NCNRs), by encapsulating Co into nanorods, activating CaSO3 for antibiotic degradation. Compared Na2SO3 NaHSO3, slowly persistently discharge SO32– due its low solubility, thus avoiding depletion generated SO3•– •OH under high concentration sulfite ions. Fully physical characterizations confirmed that 3D hydrogel was mostly transformed nanorod structure Co-NCNRs at 550 °C. atoms were successfully nanoconfined which contributes prevents agglomeration nanoparticles, enhancing catalytic activity stability water decontamination. The performance, kinetic research, influences inorganic anions, pH, degradation mechanism chlortetracycline catalyzed Co-NCNRs/CaSO3 system have been studied detail. This work not only proposed facile method synthesis catalyst but also provided an excellent wastewater treatment.

Abstract In essence, electrocatalytic CO 2 reduction reaction (CO RR) process for the ‐to‐CO conversion involves two critical reactive intermediates: *COOH and *CO. The trade‐off between adsorption of desorption *CO is challenging Ni‐based RR catalysts. high‐valence Ni site inadequate in supplying sufficient electrons activation subsequent *COOH; conversely, metallic with abundant electron exhibits excessively strong π‐backbonding *CO, thus hindering its desorption. Here, study reports a low‐coordinated single atom catalyst (SAC) characterized by structure carbon coordination, thereby engineering moderate depletion at sites. This SAC achieves high selectivity production up to 99.1% H‐cell. Additionally, it maintains an ultrahigh near 100% across broad range current densities flow cell, coupled sustained stability large 250 mA cm −2 20 h. Both situ characterization results density functional theory (DFT) calculations confirm dual functionality this structure, as enhances while concurrently facilitating greatly promoting overall process.
