High‐Alkaline Water‐Splitting Activity of Mesoporous 3D Heterostructures: An Amorphous‐Shell@Crystalline‐Core Nano‐Assembly of Co‐Ni‐Phosphate Ultrathin‐Nanosheets and V‐ Doped Cobalt‐Nitride Nanowires (Adv. Sci. 23/2022)

Water‐Splitting In article number 2201311, Seunghyun Lee and co‐workers demonstrate excellent water‐splitting activity of 3D mesoporous heterostructures assembled from CoNiPO(x)‐nanosheets amorphous‐shells and V‐doped Co(4)N nanowires crystalline‐cores on Ni foam substrate. The synergistic effect between the crystalline‐core and amorphous‐shell results remarkable oxygen and hydrogen evolution reaction at low overpotentials. [Image: see text]
