Anode Materials Requirements for Potassium Ion Batteries: Challenges and Future Possibilities

open access: yesEcoEnergy, EarlyView.
This work identifies a critical scale‐up gap between laboratory battery research and industrial targets, driven by low active‐mass loadings and the omission of full‐cell metrics. We outline concrete strategies to bridge this divide, shifting focus toward high‐loading electrodes (> 3 mg cm−2) to ensure practical commercial viability of potassium ion ...

Electron‐Hole Trap Regulation in Porous Ultrathin g‐C3N4 Nanosheet for Enhanced Photocatalytic H2 Evolution and CO2 Reduction

open access: yesEcoEnergy, EarlyView.
The porous ultrathin nanosheet morphology enhances bulk‐to‐surface charge‐carrier migration and reduces the interlayer distances in MCN‐NS. Additionally, the S‐C and N‐N bonds formed after S/N co‐doping in MCN‐NS served as electron and hole trapping sites reducing the charge recombination rate, thereby improving the photocatalytic H2 evolution and CO2 ...

Oxygen Vacancy‐Rich S‐Scheme Heterojunction Photocatalyst With Enhanced Interfacial Charge Transfer for Round‐the‐Clock Formaldehyde Degradation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work addresses the critical challenges of severe charge recombination and the dependence on constant light illumination in photocatalysis. We propose a strategy centered on an oxygen vacancy‐rich S‐scheme heterojunction, which enables precise regulation of charge carrier behavior and achieves long‐lasting photocatalytic performance.
