Oxygen Evolution Reaction: Core–Shell Structured NiFeSn@NiFe (Oxy)Hydroxide Nanospheres from an Electrochemical Strategy for Electrocatalytic Oxygen Evolution Reaction (Adv. Sci. 10/2020)

In article number 1903777, Xian-Zhu Fu, Jing-Li Luo, and co-workers prepare core–shell structured NiFeSn@NiFe (oxy)hydroxide nanospheres by a novel electrochemical strategy. Due to the synergism of the metallic core and the amorphous, defect-rich shell, the NiFeSn@NiFe (oxy)hydroxide nanospheres display an excellent activity toward the oxygen evolution reaction.
