Advancing Energy Materials by In Situ Atomic Scale Methods

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Uncovering the Role of Intrinsic Magnetic Order in Oxygen Evolution Reaction Activity With Operando Spectroscopy

Advanced Energy Materials, EarlyView.
Operando magnetic spectroscopy provides insight into how intrinsic magnetic order modulates the oxygen evolution reaction on La0.67Sr${\rm La}_{0.67}{\rm Sr}$0.33MnO$_{0.33}{\rm MnO}$3$_3$ thin films. Temperature‐dependent operando FMR and ambient‐pressure XMCD suggest a correlation between activity and the emergence of ferromagnetic regions near and ...

Ultrasound–Calcination Synergistic Control of (Ce, La)PO4 Catalyst Structure for Enhanced Low‐Temperature NH3‐SCR Performance

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, (Ce, La)PO4 catalysts were synthesized via an ultrasound‐assisted method. The effects of ultrasound duration and calcination temperature on the low‐temperature NH3‐SCR performance were systematically investigated. The results indicated that the (Ce, La)PO4 catalyst prepared with an ultrasound treatment time of 20 min and a ...
