@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
