Abstract

The invention discloses a molybdenum disulfide nano tube and a preparation method thereof. The invention takes ammonium thiomolybdate ((NH4)2MoS4) as raw material, uses AAO (anodic aluminum oxide) as a template, uses hydrogen (H2) as a reducer, uses nitrogen (N2) as protective gas and controls the growth direction of products by restrictive effect of upper holes of the template, thus synthetizing a molybdenum disulfide nano tube array with high isotonicity in size and growth orientation by large amount under the relative low temperature condition and solving the problem of the size and size distribution of the molybdenum disulfide nano tube. The method has simple technique and low cost; and the prepared molybdenum disulfide nano tube can be widely used as a solid lubricating agent, a hydrodesulfurization catalyst, a semiconductor material, an intercalation material and an anhydrous lithium battery material and the like, and is applicable to large-scale industrial production.

Description

technical field [0001] The invention relates to the field of nanomaterials, in particular, a molybdenum disulfide (MoS 2 ) nanotubes and methods for their preparation. Background technique [0002] Molybdenum disulfide has a lamellar structure similar to graphite, with strong covalent bonds within the layers and weak Van der Waals forces between the layers, and the layers are easy to peel off, so it has good anisotropy and low coefficient of friction; molybdenum disulfide nanomaterials are still excellent in lubricating performance and anti-load capacity under special working conditions such as high load, high vacuum, high / low temperature, strong radiation and strong corrosion. It is widely used in many fields such as lithium-ion battery electrodes, hydrogen storage materials, host-guest compounds, scanning tunneling microscope (STM) probes, and industrial hydrodesulfurization catalysts. So far, people have done a lot of research on the synthesis of molybdenum disulfide na...
