Abstract Na 3 V 2 (PO 4 ) , based on multi‐electron reactions between 3+ /V 4+ 5+ is a promising cathode material for SIBs. However, its practical application hampered by the inferior conductivity, large barrier of and stepwise phase transition. Herein, these issues are addressed constructing medium‐entropy (Na 3.2 1.1 Ti 0.2 Al Cr Mn Ni 0.1 ME‐NVP) with strong ME─O bond highly occupied Na2 sites. Benefiting from effect, ME‐NVP manifests phase‐transition–free reaction mechanism, two reversible plateaus at 3.4 (V 4.0 ), small volume change (2%) during + insertion/extraction processes, as confirmed comprehensive in/ex situ characterizations. Moreover, kinetics analysis illuminates superior diffusion ability ME‐NVP. Thus, realizes remarkable rate capability 67 mA h g −1 50C long‐term lifespan over 10 000 cycles (capacity retention 81.3%). Theoretical calculations further illustrate that weak binding ion in channel responsible rapid diffusion, accounting kinetics. rigid MEO 6 octahedral feasible rearrangement ions can suppress transition, thus endowing an ultrastable cathode. This work highlights significant role engineering advancing output voltage, cycling stability, polyanionic cathodes.

Enhanced photothermal methane dry reforming through electronic interactions between nickel and yttrium

Nanoscale Horizons, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 1, 2025

In this study, a Y-doped Ni-based photothermal catalyst (NiY/KCC-1) was designed for the DRM reaction. Y–Ni electron transfer stabilizes more active sites (Ni 0 ), and then enhances effect, leading to excellent catalytic performance.
