Single-atom catalysts based on metal-N4 moieties and anchored carbon supports (defined as M-N-C) are promising for oxygen reduction reaction (ORR). Among those, M-N-C with 4d 5d transition metal (TM4d,5d) centers much more durable not susceptible to the undesirable Fenton reaction, especially compared 3d ones. However, ORR activity of these TM4d,5d-N-C is still far from satisfactory; thus far, there few discussions about how accurately tune ligand fields single-atom TM4d,5d sites in order...
Abstract Layered transition metal oxides are appealing cathodes for sodium‐ion batteries due to their overall advantages in energy density and cost. But stabilities usually compromised by the complicated phase oxygen redox, particularly when operating at high voltages, leading poor structural stability substantial capacity loss. Here an integrated strategy combing high‐entropy design with superlattice‐stabilization extend cycle life enhance rate capability of layered is reported. It shown...
Doped LiNiO2 has recently become one of the most promising cathode materials for its high specific energy, long cycle life, and reduced cobalt content. Despite this, degradation mechanism derivatives still remains elusive. Here, by combining in situ electron microscopy first-principles calculations, we elucidate atomic-level chemomechanical pathway LiNiO2-derived cathodes. We uncover that O1 phase formed at voltages acts as a preferential site rock-salt transformation via two-step involving...
High-nickel content cathode materials offer high energy density. However, the structural and surface instability may cause poor capacity retention thermal stability of them. To circumvent this problem, nickel concentration-gradient have been developed to enhance high-nickel materials' cycling stability. Even though promising, fundamental mechanism concentration gradient's stabilization effect remains elusive because it is inseparable from nickel's valence gradient effect. isolate understand...
Abstract Atom segmentation and localization, noise reduction deblurring of atomic-resolution scanning transmission electron microscopy (STEM) images with high precision robustness is a challenging task. Although several conventional algorithms, such has thresholding, edge detection clustering, can achieve reasonable performance in some predefined sceneries, they tend to fail when interferences from the background are strong unpredictable. Particularly, for STEM images, so far there no...
The rechargeability of aqueous zinc metal batteries is plagued by parasitic reactions the anode and detrimental morphologies such as dendritic or dead zinc. To improve reversibility, hereby we report a new solution structure electrolyte with hydroxyl-ion scavengers hydrophobicity localized in solvent clusters. We show that although sounds counterintuitive for an system, hydrophilic pockets may be encapsulated inside hydrophobic outer layer, anode–electrolyte interface can generated through...
Selective electrochemical two-electron oxygen reduction is a promising route for renewable and on-site H2O2 generation as an alternative to the anthraquinone process. Herein, we report high-performance nitrogen-coordinated single-atom Pd electrocatalyst, which derived from Pd-doped zeolitic imidazolate frameworks (ZIFs) through one-step thermolysis. High-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) combined with X-ray absorption spectroscopy verifies...

Abstract Piezocatalytic pure water splitting for H 2 evolution carries the virtues of efficacious utilization mechanical energy, easy operation, and high value‐added products, while lacking desirable piezoelectrics chemical energy production. Here, two polar layered bismuth‐rich oxyhalides Bi 4 O 5 X (XBr, I) thin nanosheets (≈4 nm) are first exploited as efficient piezocatalysts to be capable dissociating water. The unique asymmetrical structures composed interleaved [Bi ] 2+ layer double...
It is desirable to regulate charge migration synergistically via atomic level decoration because it can construct active sites with both thermodynamic and kinetic advantages in photocatalytic hydrogen (H2) evolution. Here, a mild cation exchange-mediated strategy was applied anchor palladium (Pd) cations the ZnIn2S4 nanostructure, achieving an outstanding H2 evolution rate of 1236.4 μmol h–1 (λ ≥ 420 nm) accompanied by apparent quantum efficiency 60.06% = nm). Pd dopants act as surface...
Deep sodium extraction/insertion of cathodes usually causes undesired Jahn-Teller distortion and phase transition, both which will reduce structural stability lead to poor long-cycle reliability. Here we report a zero-strain P2- Na2/3 Li1/6 Co1/6 Mn2/3 O2 cathode, in the lithium/cobalt substitution contributes reinforcing host structure by reducing Mn3+ /Mn4+ redox, mitigating distortion, minimizing lattice change. 94.5 % Na+ unit can be reversibly cycled with charge cut-off voltage 4.5 V...
