Flower-like NiZnCu composite microstructures assembled by nanosheets as a highly active bifunctional electrocatalyst for urea-assisted energy-saving hydrogen production

Flower-like NiZnCu microstructures assembled by nanosheets are electrochemically deposited on NF at room temperature. The deposited NiZnCu microstructures serve as a bifunctional electrocatalyst for HER and UOR.
