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 ...

Recent Advances in Photocatalytic Urea Synthesis via C−N Coupling From C/N‐Containing Species: A Mini Review

EcoEnergy, EarlyView.
This review systematically compares photocatalytic urea synthesis from various C (CO2, CO, CH3OH) and N (N2, NH3, NO3−) sources. It highlights C–N coupling mechanisms, key challenges, and future directions, offering a framework to guide rational catalyst design for sustainable, solar‐driven urea production.

Bottlenecks‐Breaking in Zinc‐Iodine Batteries Toward Practical Implementation: A Review and Perspective

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Aqueous zinc–iodine batteries (Zn–I2Bs) offer promise for grid storage due to safety and cost advantages yet face critical bottlenecks: severe self‐discharge (polyiodide shuttling and HER), limited energy density, sluggish kinetics, and zinc anode instability.
