- Herein we converted Fe–Ni hydroxide nanosheets into an Fe–Ni phosphide nanoparticle-stack array on Ni foam by low-temperature phosphorization treatment for promoting the specific surface area of Fe–Ni phosphide and further improving its oxygen evolution reaction (OER) activities. The alkaline electro-activated Fe–Ni–P nanoparticle-stack array exhibits exceptional OER activities in both alkaline and neutral media.
