Entropy‐Controlled Exsolution of Highly Dispersed Nickel‐Based Active Metals From Spinel Oxide via Optimizing Metal‐Support Interaction for Dry Reforming of Methane

Carbon Energy, EarlyView.
The incorporation of transition‐metal elements into spinel oxides results in enhanced configurational entropy and increased metal‐support interaction, which continuously modulate the exsolution of nickel‐based active metal. The highly dispersed nickel‐based metal catalyst, formed through the entropy‐controlled strategy, demonstrates remarkable activity

Enhancing the d–Electrocatalytic Activity of MXene Through Defect Engineering

Carbon Energy, EarlyView.
Applications of MXene. ABSTRACT Due to their versatile and tunable surface and bulk chemistry, MXenes have great potential as electrocatalysts for batteries and supercapacitors. When compared with other electrocatalytic processes, in electrocatalytic reactions, MXenes could improve ion diffusion and charge transfer by either providing functional groups

A Fast and Highly Stable Aqueous Calcium‐Ion Battery for Sustainable Energy Storage

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Aqueous batteries provide a low‐cost, safer alternative to lithium‐ion batteries, but their viability is often limited by rapid electrode degradation. This study shows that replacing K+ with divalent Ca2+ ions in the electrolyte significantly boosts the stability of both copper hexacyanoferrate cathodes and polyimide anodes, enabling fast‐charging ...

Aqueous Supercapacitor with Wide‐Temperature Operability and over 100,000 Cycles Enabled by Water‐in‐Salt Electrolyte

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
This study presents a symmetric supercapacitor with activated carbon electrodes and a “water‐in‐salt” electrolyte (WiSE) based on lithium perchlorate, offering over 100,000 cycles with over 90 % capacity retention. The supercapacitor operates efficiently from −20 to 80 °C, enhancing performance, stability, and all‐season operability.
