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 ...

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 ...

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 ...
