Understanding Multi‐Stage Charge Storage on Nanoporous Carbons in Zn‐Ion Hybrid Capacitors

open access: yesAdvanced Materials, EarlyView.
Porous carbons with tunable pore sizes are synthesized to investigate the impact of pore size on charge storage in Zn‐ion hybrid capacitors. An unusual multi‐stage charge storage mechanism is revealed, involving a transition from capacitive Zn2+ ion storage to faradaic Had adsorption on the carbon surface, providing new insights into Zn‐ion ...

High‐Entropy Materials for Water Splitting: An Atomic Nanoengineering Approach to Sustainable Hydrogen Production

open access: yesAdvanced Materials, EarlyView.
High‐entropy materials (HEMs), typically composed of five or more principal elements in near‐equimolar ratios, offer significant potential due to their unique properties. This review outlines the emergence and structural evolution of HEMs, followed by an in‐depth discussion of the elemental roles (active sites, promoters, or stabilizers) for water ...

Ultra‐low LOD H2O2 Sensor Based on Synergistic Nernst Potential Effect

open access: yesAdvanced Science, EarlyView.
Due to the synergistic effect of ENernst,H2O2${E}_{\mathrm{Nernst},\ {\mathrm{H}}_{2}{\mathrm{O}}_{2}}$ and ENernst,H+${E}_{\mathrm{Nernst},\ {\mathrm{H}}^{+}}$, the proposed sensors in this study can achieve ultralow H2O2 detection limit as low as 1.8 × 10−12 M based on the stacked PEDOT: BTB/PEDOT: PSS semiconducting layer.

Potential‐Driven Dynamic Spring‐Effect of Pd─Cu Dual‐Atoms Empowered Stability and Activity for Electrocatalytic Reduction

open access: yesAdvanced Science, EarlyView.
The dynamic “spring‐like” behavior of Pd─Cu dual atoms with PdN3─CuN3 coordination structure can be stretched and recovered with potential variation, which remarkably elevates the structural stability and catalytic activity of Cu atoms for electrocatalytic reduction reactions in strong‐acid electrolytes. The modulated electron‐orbit coupling effect and
