title: Surface-Charge-Mediated Formation of H-TiO2@Ni(OH)2Heterostructures for High-Performance Supercapacitors.
abstract: An electrochemically favorable Ni(OH)2with porously hierarchical structure and ultrathin nanosheets in a core-shell structure H-TiO2@Ni(OH)2is achieved through modulating the surface chemical activity of TiO2by 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)2core-shell nanowires exhibit a superior electrochemical performance and good flexibility.
