Surface‐Charge‐Mediated Formation of H‐TiO2@Ni(OH)2 Heterostructures for High‐Performance Supercapacitors

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 s...
