Abstract Highly porous nanostructures with large surface areas are typically employed for electrical double-layer capacitors to improve gravimetric energy storage capacity; however, high area carbon-based electrodes result in poor volumetric capacitance because of the low packing density materials. Here, we demonstrate ultrahigh 521 F cm −3 aqueous electrolytes non-porous carbon microsphere co-doped fluorine and nitrogen synthesized by low-temperature solvothermal route, rivaling expensive...
Oxygen vacancies (OVs) are important for changing the geometric and electronic structures as well chemical properties of MnO2. In this study, we performed a DFT+U calculation on structure catalytic performance β-MnO2 catalyst oxygen reduction reaction (ORR) with different numbers extents OVs. Comparing those results experimental XRD analysis, determined that OVs produce new crystalline phase β-MnO2. Changes in (Bader charges, band structure, partial density states, local frontier molecular...
Abstract A zinc‐based single‐atom catalyst has been recently explored with distinguished stability, of which the fully occupied Zn 2+ 3d 10 electronic configuration is Fenton‐reaction‐inactive, but catalytic activity thus inferior. Herein, we report an approach to manipulate s‐band by constructing a B,N co‐coordinated Zn‐B/N‐C catalyst. We confirm both experimentally and theoretically that unique N 2 ‐Zn‐B crucial, in + (3d 4s 1 ) can hold enough delocalized electrons generate suitable...
Half metal, with moderate delocalized and parallelized arrangement of spin freedom, is crucial to optimize the bifunctional catalyst for both ORR OER, atomic magnetization on reaction center could serve as a activity descriptor.
The emergence of atomically thick nanolayer materials, which feature a short ion diffusion channel and provide more exposed atoms in the electrochemical reactions, offers promising occasion to optimize performance supercapacitors on atomic level. In this work, novel monolayer Ni-Co hydroxyl carbonate with an average thickness 1.07 nm is synthesized via ordinary one-pot hydrothermal route for first time. This unique structure can efficiently rise up electroactive sites facilitate surface...
An efficient non-noble bifunctional electrocatalyst for both the oxygen evolution reaction (OER) and hydrogen (HER) in same electrolyte.
The catalytic performance of Pt-based catalysts for oxygen reduction reactions (ORR) can generally be enhanced by constructing high-index exposed facets (HIFs). However, the synthesis Pt alloyed skins on 1D non-Pt surfaces to further improve utilization and stability remains a fundamental challenge practical nanocrystals. In this work, Pd nanowires (NWs) are selected as rational medium facilitate epitaxial growth Ni. Based different nucleation habits Ni, continuous PtNi alloy skin bounded...
Aqueous hybrid capacitors (HCs) suffer from sacrificed power density and long cycle life due to the insufficient electric conductivity poor chemical stability of battery-type electrode material. Herein, we report a novel NH4-Co-Ni phosphate with stable hierarchical structure combining ultrathin nanopieces single crystal microplatelets in one system, which allows for synergistic integration two microstructures different length scales energy storage mechanisms. The store charge through...

We report a combined experimental and computational study on exfoliated montmorillonite (ex-MMT) nanoplatelet supported palladium catalysts. The results revealed that the Pd/ex-MMT catalysts were more stable than Pd/C in an acidic environment. from density functional theory (DFT) calculations O atoms AlO6 octahedra ex-MMT act as anchoring sites for Pd nanoparticles (NPs) are strongly bound to support. partial of state indicated Pd-d states O(AlO6)-p have similar energy. Therefore, it is very...
