One-dimensional hierarchical Ni3S2@MoS2 core/shell nanorod arrays on Ni foam synthesized using a one-step hydrothermal method exhibit a higher specific capacitance with better cycling performance than bare Ni3S2 sample. Broad Context. Hybrid core/shell heterostrucutres have been widely investigated for high-performance supercapacitors. With two functional materials constructed in a programmed way, desired properties and multifunctionality can be achieved by fine-tuning their compositions, shapes, and controlled alignments. Hierarchical nanostructures are always favoured for electrodes of supercapacitors due to high reaction area, fast ion and electron transport and improved rate properties. In this paper, we provide a facile one-step strategy for the fabrication of hybrid core/shell metal sulfides with a conductive Ni3S2 core. Using Ni3S2@MoS2 as an example, we demonstrate that hierarchical core/shell metal sulfides shows evidently better performance in the supercapacitor test than the bare Ni3S2 core. It is anticipated that such a unique core/shell nanostructure will have potential applications in supercapacitor, lithium-ion batteries, electrochemical or photocatalysis devices and energy conversion storage. Importantly, our study can be extended to the synthesis of other Ni3S2 based hybrid metal sulfides.
