Abstract

An electrochemically favorable Ni(OH)2 with porously hierarchical structure and ultrathin nanosheets in a core–shell structure H‐TiO2@Ni(OH)2 is achieved through modulating the surface chemical activity of TiO2 by hydrogenation, which creates a defect‐rich surface of TiO2, thereby facilitating the subsequent nucleation and growth of Ni(OH)2. These configuration‐tailored H‐TiO2@Ni(OH)2 core–shell nanowires exhibit a superior electrochemical performance and good flexibility.
