Enabling the full exposure of Fe2P@NixP heterostructures in tree-branch-like nanoarrays for promoted urea electrolysis at high current densities

It’s highly desirable but still challenging, through the structure construction strategy, to design brilliant bifunctional electrocatalysts for the urea oxidation reaction (UOR) and hydrogen evolution reaction (HER) with both fast electron and mass transport, especially under high current densities. Herein, a novel tree-branch-like Fe2[email protected]xP heterostructure nanoarrays on NF (denoted as Fe2[email protected]xP/NF) were fabricated as...
