Kirkendall‐Effect‐Mediated Hollow Bimetallic Hexacyanoferrates for Aqueous Zn‐Ion Batteries: Suppressing Jahn–Teller Distortions and Enhancing Ion Transport and Cyclability

Carbon Energy, EarlyView.
Kirkendall‐engineered hollow Ni–Mn hexacyanoferrates feature Ni‐tunable shell thickness and uniform alloying, coupling architectural control with electronic stabilization. Composition–morphology co‐optimization suppresses Mn³⁺‐driven Jahn–Teller distortions and lowers charge‐transfer barriers, enabling rapid Zn²⁺ transport and reversible redox.

Direct Capture of Dynamic Surface Reconstruction in a Perovskite Cathode via Operando Raman Spectroscopy

Carbon Energy, EarlyView.
Operando Raman spectroscopy directly captures the dynamic form conditions of the BaCoO3‐δ phase on the BSCY surface. This observation provides critical insight into the phase evolution mechanisms, which are essential for optimizing the performance and stability of BSCY‐based protonic ceramic fuel cell cathodes.

Ruthenium‐Titania Interface‐Mediated Water Activation for High Turnover Frequency in Alkaline Hydrogen Evolution

Carbon Energy, EarlyView.
Heterostructured interfaces can accelerate hydrogen evolution by improving water dissociation, yet their underlying mechanisms remain unclear. This study combines in situ Raman spectroscopy and density functional theory to reveal how the RuO2/TiO2 interface promotes both water dissociation and hydrogen adsorption, providing new insights into the ...

Harnessing Native Al/Si Impurities in Bamboo Black Liquor for Self‐Templated Closed‐Pore Hard Carbon Anodes

Carbon Energy, EarlyView.
A scalable strategy utilizing native impurities in bamboo lignin black liquor is proposed to construct a closed‐pore, rich hard carbon. Controlled impurity removal and high‐temperature reconstruction enable the conversion of open pores into abundant closed pores, thereby promoting sodium cluster storage.

Positional Isomer Engineering for Crystallization Kinetics Control in Wide‐Bandgap Perovskite Solar Cells

Carbon Energy, EarlyView.
Based on the ortho‐para configuration of the amino‐sulfonic acid group, 2,4‐diaminobenzenesulfonic acid (2,4‐DABSA) forms the strongest coordination with the perovskite precursor among its isomers, guiding a unique “fast nucleation followed by slow crystallization” kinetics.
