Toward Understanding the Stability of Single‐Atom Catalysts in Oxygen Evolution Reactions

open access: yesAdvanced Energy Materials, EarlyView.
Enhancing the stability of single‐atom catalysts for the oxygen evolution reaction hinges on understanding support interactions, local geometry, and structural dynamics. Transitioning to OH‐modified surfaces offers a promising route to cap surface metals and prevent leaching, paving the way for the next generation of stable OER SACs.

Metal Sulfides as Potential Materials for Next Generation Lithium Ion Batteries: A Review

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The flame spray pyrolysis (FSP) method demonstrates its superiority in fabricating metal sulfide‐based electrodes without inactive materials like organic binders or solvents. The particles are directly deposited and compressed onto the electrode surface, integrating into continuous production.
