To enhance structural stability and explore energy storage mechanisms for sodium-ion batteries, Ni3S2 nanoparticles anchored on d-Ti3C2 nanosheets (Ni3S2/d-Ti3C2) are designed and synthesized through the hydrothermal method followed by sulfurization reaction. Ni3S2/d-Ti3C2 provides abundant active sites and reduces the Na+ diffusion path, leading to high sodium storage performance. The d-Ti3C2 nanosheets work as a conductive framework, providing high ion- and electron-conductive pathways and buffer volume change in Ni3S2 nanoparticles, while Ni3S2 nanoparticles exhibit high sodium storage and are applied as the spacer to suppress the restacking of d-Ti3C2 nanosheets. The synergistic effect effectively improves sodium storage performance of the obtained electrode and shows a special capacitive and diffusive dual-model energy storage mechanism for sodium-ion batteries. Specifically, Ni3S2 nanoparticles are battery-type components with high capacity, and the d-Ti3C2 nanosheets are pseudocapacitive components with a high pseudocapacitive value and fast energy storage. Consequently, the Ni3S2/d-Ti3C2 electrode provides enhanced performance (234.4 mA h g–1 at 0.1A g–1), almost 5.5 times that of the d-Ti3C2 electrode (∼42.4 mA h g–1). The results show that this metal sulfide incorporation strategy presents a prospective way to heighten sodium storage performance of d-Ti3C2 MXene.

The unique electronic and catalytic properties emerging from low symmetry anisotropic (1D and 2D) metal chalcogenides (MCs) have generated tremendous interest for use in next generation electronics, optoelectronics, electrochemical energy storage devices, and chemical sensing devices. Despite many proof-of-concept demonstrations so far, the full potential of anisotropic chalcogenides has yet to be investigated. This article provides a comprehensive overview of the recent progress made in the synthesis, mechanistic understanding, property modulation strategies, and applications of the anisotropic chalcogenides. It begins with an introduction to the basic crystal structures, and then the unique physical and chemical properties of 1D and 2D MCs. Controlled synthetic routes for anisotropic MC crystals are summarized with example advances in the solution-phase synthesis, vapor-phase synthesis, and exfoliation. Several important approaches to modulate dimensions, phases, compositions, defects, and heterostructures of anisotropic MCs are discussed. Recent significant advances in applications are highlighted for electronics, optoelectronic devices, catalysts, batteries, supercapacitors, sensing platforms, and thermoelectric devices. The article ends with prospects for future opportunities and challenges to be addressed in the academic research and practical engineering of anisotropic MCs.
