METAL TYPE MOLYBDENUM DISULFIDE QUANTUM DOT-MODIFIED TIN NANOTUBE ARRAY COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR

摘要

The present invention relates to the technical field of preparation of nanomaterials, and in particular, to a metal type molybdenum disulfide quantum dot-modified TiN nanotube array composite material and a preparation method therefor. The preparation method comprises: (1) using a manual grinding method to grind a large-size semiconductor MoS2 block to obtain the semiconductor MoS2 powder; (2) performing lithium intercalation treatment on the semiconductor MoS2 powder; (3) dispersing the semiconductor MoS2 powder subjected to the lithium intercalation treatment into a solvent, performing ultrasonic treatment, and performing centrifugal separation to obtain a metal type MoS2 quantum dot solution; (4) placing a TiN nanotube array into the metal type MoS2 quantum dot solution, and then sequentially performing ultrasonic treatment, immersing same, and drying same to obtain the metal type MoS2 quantum dot-modified TiN nanotube array composite material. The metal type MoS2 quantum dot-modified TiN nanotube array composite material of the present invention has excellent electrocatalytic performance and stability.
