Herein, a patterned rod‐like CoP@NiCoP core‐shell heterostructure is designed to consist of CoP nanowires cross‐linked with NiCoP nanosheets in tight strings. The interfacial interaction within the heterojunction between the two components generates a built‐in electric field that adjusts the interfa...
