Corrosion of Candidate Materials for Use in Alkaline Water Electrolysis

CORROSION 2019, 2019
Abstract In alkaline water electrolysis the capital expense (CAPEX) of the electrolyzer unit is high and cost reduction, wherever possible, is highly desired. Many parts are made of expensive nickel-based alloys, which in some cases may be an overly conservative option.

Operando X‐Ray Absorption Spectroscopy Reveals Dynamic Interfacial Metal–Metal Coordination Governing CO2 Reduction Selectivity in PdAg Alloys

Advanced Materials Interfaces, EarlyView.
Operando X‐ray absorption spectroscopy uncovers dynamic Ag–Pd coordination in PdxAg1−x electrocatalysts during CO2 reduction. Partial oxidation of Ag and composition‐dependent metal–metal bonding synergistically regulate intermediate binding, enabling ∼91% CO selectivity.
