Method is presented for crystalline molybdenum disulfide (MoS2) inorganic nanotubes (INTs) production. Initial synthesis of pure phase hexagonal molybdenum oxide (h-MoO3) nanowhiskers is performed forming precursor and templating agent for MoS2 INTs production. First-stage sulfurization of h-MoO3 is performed via a solid-gas reaction at first temperature conditions T1 producing MoOx-containing nanowhiskers (2≤x<3) followed by formation of initial growth stage of MoS2 INTs being nanostructures having cores with MoOx-containing nanowhiskers and initial MoS2 intermittent guiding layers being randomly oriented nanoplatelets or partially distorted layers at surface of MoOx-containing nanowhiskers. Second or successive second and third stages of sulfurization of said nanostructures is/are performed providing recrystallization of MoS2 intermittent guiding layers to obtain highly crystalline layers and complete sulfurization of MoOx inside the cores to MoS2, and obtain pure phase and high aspect ratio MoS2 INTs of needle-like crystal with hollow core morphology, and predetermined walls' structure.
