Description

technical field

[0001] The invention relates to the technical field of energy storage materials, in particular to a metallic 1T molybdenum disulfide nanosheet array and its preparation method and application. Background technique

[0002] Transition metal sulfides are materials that realize lithium ion intercalation through conversion reactions, and have high theoretical capacity, but their cycle performance is poor. Among all the reported transition metal sulfides, molybdenum disulfide nanomaterials with graphite-like structure have attracted attention due to their potential applications in catalysis, hydrogen storage materials, lithium-ion electrode materials, etc.

[0003] MoS 2 The molecular layer is composed of the middle layer of Mo atoms and the upper and lower layers of S atoms connected by strong covalent bonds, and the layers are stacked by weak van der Waals force. Molybdenum disulfide mainly has two crystal phases, one is the 2H phase with a triangular prism st...
