Relationship between structural features of MoS_2 nanotubes and crystalline structure of precursor

摘要

MoS_2 nanotubes have been synthesized by thermal decomposition of ammonium thiomolybdate (ATM) precursor and by using the aluminum oxide template method. Hollow tubes of very specific diameter and wall thickness were obtained presenting the so-called "bamboo" texture. These nanotubes are closed in sections; each one 29 nm wide and a length of 63 nm in average. Evidence of a strong relationship between these structural features of MoS_2 nanotubes and crystalline structure of precursor is exposed, suggesting that both size and shape of tube sections are determined by crystalline structure of ATM precursor as well as by the diameter of template pores.
