Morphology‐Dependent Reconstruction Generates One‐Dimensional Catalysts for Durable Urea‐Assisted Water Electrolysis at Industrial Current Density

ABSTRACT Designing cost‐effective and durable catalysts for the urea oxidation reaction (UOR) at industrial current density is key to materializing UOR‐assisted water electrolysis for green hydrogen production while remedying environmental urea pollution. Here, we discovered the morphology‐dependent in situ reconstruction to transform copper‐based two‐dimensional nanosheets and zero‐dimensional cubes into one‐dimensional copper hydroxide (Cu(OH) 2 ) nanowires and nanoneedles, respectively, for e
