Rational Design and Operando Characterization of Hierarchical α‐FeOOH‐FeP/Ni3S2 Catalysts for High‐Rate Alkaline Water Electrolysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A hierarchical FeOOH–FeP@Ni3S2 electrocatalyst is engineered on 3D Ni foam to enable efficient alkaline oxygen evolution. Operando spectroscopic techniques reveal dynamic surface reconstruction and proton‐coupled electron transfer (PCET) kinetics. The catalyst exhibits low overpotential and industrial‐level current operation, driving high‐performance ...

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.

Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and
