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.
