The #element #chromium plays a crucial role in this process.
Although chromium itself is not an active element, its continuous dissolution enables a reversible surface transformation that keeps the Co-Cr spinel oxide #electrocatalyst active and stable.

Extending the Lifespan of Electrocatalysts

A research team has discovered how to keep a cobalt-based oxide electrocatalyst active and stable.

Researchers from Fraunhofer UMSICHT, Ruhr-University Bochum and University of Bayreuth have developed a bifunctional #electrocatalyst made from iron nickel sulfide (FeNi2S4 [FNS]) for the overall electrochemical water splitting. #GreenHydrogen #Hydrogen

@sflorg In this work (https://www.science.org/doi/full/10.1126/sciadv.adf6075), the authors present a synthetic bottom-up approach to fabricate 3D #nanostructures with nanoscale dimensions, bridging the gap between molecular and micrometer-sized 3D materials. "The surfaces can be chemically modified by a catalytically active material. The effectiveness as #electrocatalyst support materials is shown by the high #OER activity and stability of Ni/Fe-O(OH)–coated 3D nanostructures." #Electrocatalysis #OxygenEvolutionReaction
