Electrolytic Damage in Zirconia Electrolytes

ECS Proceedings Volumes, 2003
Yttria stabilized zirconia (YSZ) electrolytes, subjected to high current densities, develop significant damage. This paper characterizes the damage that develops from the anode side, in YSZ used in an oxygen pump configuration. The damage is in the form of vacancy loops, precipitates formed on dislocations, pore development, and grain boundary fracture.

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites

Advanced Functional Materials, EarlyView.
We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...
