Abstract Routine electrolyte additives are not effective enough for uniform zinc (Zn) deposition, because they hard to proactively guide atomic‐level Zn deposition. Here, based on underpotential deposition (UPD), we propose an “escort effect” of at the atomic level. With nickel ion (Ni 2+ ) additives, found that metallic Ni deposits preferentially and triggers UPD Ni. This facilitates firm nucleation growth while suppressing side reactions. Besides, dissolves back into after stripping with...
Aqueous zinc-ion batteries (AZIBs) have experienced a rapid surge in popularity, as evident from the extensive research with over 30 000 articles published past 5 years. Previous studies on AZIBs showcased impressive long-cycle stability at high current densities, achieving thousands or tens of cycles. However, practical low densities (<1C) is restricted to merely 50-100 cycles due intensified cathode dissolution. This genuine limitation poses considerable challenge their transition...
Competition from hydrogen/oxygen evolution reactions and low solubility of N2 in aqueous systems limited the selectivity activity on nitrogen fixation reaction. Herein, we design an aerobic-hydrophobic Janus structure by introducing fluorinated modification porous carbon nanofibers embedded with partially carbonized iron heterojunctions (Fe3 C/Fe@PCNF-F). The simulations prove that can keep internal Fe3 C/Fe@PCNF-F away water infiltration endow a molecular-concentrating effect, suppressing...
High-voltage cathodes with high power and stable cyclability are needed for high-performance sodium-ion batteries. However, the low kinetics inferior capacity retention from structural instability impede development of Mn-rich phosphate cathodes. Here, we propose light-weight fluorine (F) doping strategy to decrease energy gap 0.22 eV 1.52 trigger a "Mn-locking" effect-to strengthen adjacent chemical bonding around Mn as confirmed by density functional theory calculations, which ensure...
We present the crystal-glass transformation of two-dimensional hybrid organic–inorganic perovskites (HOIPs) via ball-milling.
<title>Abstract</title> Metal anodes hold considerable promise for high-energy-density batteries but are fundamentally limited by electrochemical irreversibility caused uneven metal deposition and dendrite formation, which compromise battery lifespan safety. The chaotic ion flow (or flux vortex) near the electrode surface, driving these instabilities, has remained elusive due to limitations in conventional techniques such as scanning electron atomic force microscopies, invasive incapable of...
In this work, we investigated the response of metal-organic framework MIL-125-NH2 to ball-milling. Both localised and bulk analyses revealed prolongued ball-milling results in a complete loss long-range structural order. Investigation disorder partial retention local bonding secondary building unit, suggesting structure collapse progressed primarily through metal-linker bond breakage. We explored photocatalytic performance materials, examined materials' band gap using UV-Vis reflectance spectroscopy.
A phosphorylated GQD intercalated COF membrane simultaneously exhibits superhigh proton conductivity and outstanding mechanical strength.
Single-atom catalysts (SACs) are promising for 4e − oxygen reduction reaction (4e ORR). However, they rarely utilized in other oxygen-involved reactions, e.g. 2e ORR to produce H 2 O , evolution OER), and water oxidation (2e WOR). Herein, we applied density functional theory (DFT) calculations investigate the applicabilities of SACs, including Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Nb, Mo, Ru, Rh, Pd, Pt, Au with axial coordination (e,g, –OH, =O, ≡N) all /2e reactions. With coordination, SACs...

Melt alloying, the process of melting a physical powder blend to create homogeneous alloy, is widely used in materials processing. By carefully selecting and their proportions, properties resulting alloy can be precisely controlled. In this study, we investigate possibility utilizing melt alloying principles for meltable two-dimensional hybrid organic–inorganic perovskites (2D-HOIPs). We mixtures two selected 2D-HOIPs: glass-forming (S-NEA)2PbBr4 (S-NEA = (S)-(−)-1-(1-naphthyl)ethylammonium)...

With increasing interest in non‐crystalline systems, glassy state HOIPs has recently been identified. Here, basic building blocks crystalline appear be retained, though their glasses lack long‐range periodic order. The emerging family formed from exhibits diverse properties,...

Abstract Aqueous zinc (Zn) batteries hold great promise for large-scale energy storage by virtue of the high sustainability, low cost Zn resources, safety and environmental impact. However, severe side reactions including dendrite growth at surface hinder their practical application. “Water-in-salt” organic/aqueous hybrid electrolytes address these problems but compromise intrinsic merits ionic conductivity, superior safety, good sustainability. Herein, methylurea (MU) which has hydrogen (H)...
