Assessing the Correct Electrochemical Surface Area of Gold Electrocatalysts by Copper Underpotential Deposition

Abstract Knowing the electrochemical surface area (ECSA) is crucial to fully understand an electrocatalytic system and correctly contextualize the behavior of a catalyst. We show that the surface oxidation method poses several problems for the ECSA determination, while the copper...

Facile Ferric Nitrate Spray Fabrication and In Situ NAP-XPS Investigation of NiFeOxHy-Coated Nickel Foam Electrocatalysts for Alkaline Water Electrolysis

Abstract The development of efficient and scalable oxygen evolution reaction (OER) electrocatalysts is critical for advancing alkaline water electrolysis technologies. In this study, we present a facile spraying method for fabricating NiFeOxHy-coated nickel foam (NF) electrodes u...
