Manipulating the Corrosion Resistance of SnO₂ Aerogels through Doping for Efficient and Durable Oxygen Evolution Reaction Electrocatalysis in Acidic Media

Implementing iridium oxide (IrOx) nanocatalysts can be a major breakthrough for oxygen evolution reaction (OER), the limiting reaction in polymer electrolyte membrane water electrolyzer devices. However, this strategy requires developing a support that is electronically conductive, is stable in OER conditions, features a large specific surface area and a porosity adapted to gas–liquid flows. To address these challenges, we synthesized IrOx...
