Constructing Nanosphere Heterogeneous Structure of Ir‐Doped CoP 3 and WO 2 with Interfacial Coupling for Overall Alkaline Water/Seawater Splitting

accelerates electron transfer, enhances the conductivity of the catalyst, and improves the HER/OER performance of the catalyst through a synergistic effect. Therefore, this work provides a new idea for designing metal-doped heterostructures for electrochemical decomposition of water/seawater.
