Hierarchical α-MnO 2 nanowires@Ni1-xMnxOy nanoflakes core-shell nanostructures for supercapacitors
A facile two-step solution-phase method has been developed for the preparation of hierarchical α-MnO2 nanowires@Ni1-xMnxOy nanoflakes core–shell nanostructures. Ultralong α-MnO2 nanowires were synthesized by a hydrothermal ...
General formation of MS (M = Ni, Cu, Mn) box-in-box hollow structures with enhanced pseudocapacitive properties
Complex hollow structures of metal sulfides could be promising materials for energy storage devices such as supercapacitors and lithium-ion batteries. However, it is still a great challenge to fabricate well-defined metal ...
Self-templated formation of uniform NiCo2O4 hollow spheres with complex interior structures for lithium-ion batteries and supercapacitors
Despite the significant advancement in preparing metal oxide hollow structures, most approaches rely on template-based multistep procedures for tailoring the interior structure. In this work, we develop a new generally ...
